Dennerle Scaper's Flow: geni.us/LUcx Cheap mesh media bags (small): geni.us/DtoexHC Foams and Biohome Ultimate: www.filterpro.co.uk (FilterPro site has links to suppliers in other countries) The Dennerle scaper's flow HOB / canister filter is a really interesting design which offers a decent provision for both mechanical and biological filtration. Trays are really easy to set up with alternative media / foams and they fit together very securely to eliminate bypass. The top media tray holds around 550g of Biogravel so is really suited to normally stocked tanks of around 60 litres (16 US gallons) or heavily stocked tanks of around 30 litres (8 US gallons) if you want to achieve a full cycle. If you are using this on a well planted tank you could achieve a full cycle in 100 litres+ A full cycle is completed by bacteria - the aerobic part of biological filtration which processes ammonia to nitrite and nitrite to nitrate followed by an anaerobic part which processes nitrate into soluble nitrogen which bubbles off to the atmosphere. Therefore it requires a suitable amount of excellent quality filter media to be able to provide the environment for both aerobic AND anaerobic bacteria - that is what Biohome ultimate does perfectly but even with such good media there are limitations and we recommend the following amounts for different stocking scenarios: (1 US Gallon = 3.8 litres) (1kg = 2.2 lbs) Average community tropical aquarium = 1kg per 100 litres Average coldwater aquarium = 1kg - 1.5kg per 100 litres Predator aquarium = 1.5kg - 2kg per 100 litres Large cichlid aquarium = 1.5kg - 2kg per 100 litres Malawi / Tanganyikan aquarium = 1.5kg - 2kg per 100 litres Marine aquarium = 1.5kg - 2kg per 100 litres Average mixed fish pond = 1kg per 200 litres Average koi pond = 1kg per 150 litres You may be disagreeing with the above figures but remember that they are for a FULL CYCLE not half a job - achieving 0 ammonia and 0 nitrite is quite easy since aerobic bacteria grows freely on any surface but the anaerobic bacteria responsible for COMPLETING the cycle needs more a specialized habitat. Size a filter properly, set it up sensibly and you will have perfect water - it's that simple....and your filter won't be the dreaded 'Nitrate factory'.....you'll spend less money on treatments too......basically the filter is the foundation of a successful aquarium.

Yes first line of video description and pinned comment is link to check the filter out: Dennerle Scaper's Flow: geni.us/LUcx For shrimp, betta or fry tanks it is a great design.
Yes it would have been perfect for us when I had the shop as each shrimp tank could have been well planted with one of these on the back of each tank - cracking little filter and I was stoked to have this one sent up to feature in this series.
360 liters is exactly 95.1019 gallons so not too bad. Flow rate isn't everything. I like reliable, quiet filters that hold a decent amount of bio media not necessarily in that order so I orderd this filter for my 29 gallon tank. It looks more practical than a regular cannister filter that sits on the floor for a small tank and I hate hob filters. They all suck, I'm surprised there isn't more hybrid filters available. The Allpond Solutions filters looks like a winner especially for the price, but I can't get it in Detroit so I'm going with the Scapa Flow
Worth mentioning is the Lily pipe head on the outflow. This will create a vortex that will maximize flow. It looks as this would be great for fry and shrimp.
I was impressed with this filter when Richard showed us how to Pimp it. He was also impressed with it. I checked it out at the time and thought it was a bit expensive for my shrimp tank as I was using sponge filters. I then decided to re-scape it. Sponge filters can be good but they are ugly. After looking at other options I invested in a Dennerle Scapers Flow and I am more than satisfied. It just has a feeling of quality. Most importantly the spare parts are readily available. I replaced the media that came with it for some seeded Biogravel that was in the canister. My tank is a custom 42 litre.
Ultum Nature Systems Canister Filter for Aquariums - Delta 30 looks like the exact same filters. I just picked one of those up, and this video popped up in my feed. Looks like it is a well designed white label product.
Richard-You're awesome! Much appreciation for your videos from the U.S. Though I've been keeping aquariums for a long time, I've never been a filter guy per se. You make it interesting and fun. I don't care for the Magnum HOB filter and there really isn't a wealth of HOB canister filters. This looks to be a nice example.
Yes this one really has the best of both worlds by combining the convenience of a HOB with the capacity of a small canister. I'm glad you enjoy the videos as I put them out purely to help anyone with similar filters.
(my other channel) I've no idea if Dernnele have anything new but the best and cheapest HOB filter I've featured on this series of videos is the All Pond Solutions HOB-500. It costs pennies compared to some of the HOB filters and easily holds 1kg of Biogravel. It is excellent value - here is the video I did on that one: ruclips.net/video/XKI1ZNQ4eME/видео.html and here are the relevant links: APS HOB-500 (Amazon): geni.us/Q4AI37t APS HOB-500 (Ebay): ebay.to/2DZfrnz Smaller version (Ebay): ebay.to/2SEvMG1 Foam for intake (Amazon): geni.us/EY86zGk US Equivalent Filter Model 803 (Ebay.com): ebay.to/2MQnPZ4 US SunSun version HL-803 (Ebay.com): ebay.to/2MUr0z1 Foams and Biogravel: www.filterpro.co.uk (FilterPro site has links to suppliers in other countries)
Ive been looking for something like this for years for nano tanks and this is the first time ive seen it! Really well designed little filter. I need to find this.
Hopefully the link in the video description and pinned comment is worldwide: geni.us/LUcx It is a really great little filter with plenty of filtering capacity.
When you look at the benefits it offers over the awful HOB filters people seem to use (which rely on expensive cartridges) long term it is a good investment but initially it does cost much more than the 'normal' HOB filters (which tend to be crap)
Ive got a couple of hobs (came with the tank) and i dont use the cartridges, theyre expensive and crap i put a bit of foam in then jam in as much biohome as i can get in it.
The flow rate is actually not bad on this filter. They didn't overrate it the flowrate that's for sure. This is a really good filter for a small tank. I use it in conjunction with two Sun Sun HBL 803 hob filters on a 55 gallon African Cichlid tank all hung off the back
Hi, I have it on a 30 liter and after few days the flow is reduced. Can you explain how it comes? All is original except for the normal filter pad, I changed it with a juwel pad.
I'm looking at this filter for a nano tank. With no partition down the center of the trays, wouldn't the flow tend to bypass the sponge tray and just work across the bio media tray?
The bottom tray takes water in through the whole of the bottom so water is drawn in through the foams more or less equally. The same is true for the media tray.
thank you , i just got a delta 60 from uns and couldn't find anything on it online but this one is pretty damn similar so this was a perfect video to watch.
Hi, love this video! Quick question, if the power ever goes out, will this filter start up again or is it like most HOB that needs water to be added to start up?
It will start up again because all the water that is in the canister, remains there when it is not receiving power. The electric pump has to fight gravity to push the water up and out, so without it getting power the water will just sit there in the canister once it is already inside
Thanks for a great demo, but most of all, showing the design. Have you tested this for an electrical outage scenario ? { i was disappointed with Fluvals HOB, where after the electricity resumed, it ran dry for hours.} With this Dennerle offering i'm scratching my head with the quality of water flow direction...which looks zero. Yes it has a pump, but once the water enters the only directing element of the unit, the top tray... it's a free for all. It has stackable rooms, but no direction for maximization of the water flow through filter media. Knowing water takes the path of least resistance, the first stage sponge will only have the top surface utilized. With the design engineering as is, each tray having a center dividing wall would have fixed this weakness. I'm looking for a filter that has ease of cleaning, which this looked like it has, but it's just not there yet.
(my other channel) I don't generally run the filters in this video series since they are owned by other people (viewers) but I'd expect that most HOB filters will have similar problems if the power goes off. An external canister filter will just kick back into action when the power is restored but getting the HOB going again could be a different story.
Great stuff, I never have any idea where the videos get shared but am always grateful when they get shared or uploaded around internet land. Thanks for watching.
Thanks!! So it sounds like aside from the power / flow rate... this might be the perfect compact hang on filter? basically, we could swap out the internal pump with something a little more strong from Amazon, and it would be near flawless?
(my other channel). I don't run the filters since they are owned by viewers who send them to me but from all accounts they are very quiet. Loads of people use them in aquascaped tanks.
Hi yet again another great review, I have this filter shortlisted along with a seachem tidal power filter 35 which would you recommend for a 55 litre moderately planted tank with a betta ? Thanks again
I’m thinking to buy one but shoud i refill it with water after the electricity Disconnect like a normal hang on filter and can i control the water flow ??
i would be tempted to put tubes on to make the inlet and outlet further apart, with the inlet going to one end so its near the bottom and the outlet so it had a spray bar on to the other end of the tank, that way it would create a flow in the tank, if that would be possible
I think the idea is that the outlet is at water level so scoots water along the surface but I would like to see an option to increase the length of the inlet too - there may be that option but sometimes when people send filters I don't get all the parts - I couldn't see anything on the box or instructions about an extended intake pipe though.
the cheapest one i found on ebay is £68.99 which i think is a bit steep for the size of it, dont think my canister filter cost that and it has a uv light built in, can buy spray bars and inlet tubes and shrimp filters etc for them on ebay so would imagine you would be able to do the same for the Dennerle Scaper's Flow HOB Canister Filter, all you need to know is the pipe size........ always enjoy your videos by the way
Yes, it is quite a passive filter but would definitely keep water clear and healthy in a planted lightly stocked tank - it's not really one for a full-on fish tank though as a standard canister would have more draw and flow to keep water clean. It would have more capacity for media too but it's horses for courses.
Using the Biohome Ultimate media... Can we achieve 'full cycle' including Nitratre removal when putting the Biohome into a high flow filters such as this or other high flow HOB filters? Or is it better to use Biohome only in low flow areas of filters or tanks to achieve Nitrate removal?
A low flow will encourage a more de-oxygenated water flow and therefore promote a greater proportion of anaerobic bacteria but the biohome will still support anaerobic bacteria in tiny pockets all through its structure in any flow, even a fast flowing highly oxygenated shower filter or fast flowing canister - recommended amounts to use are found in the video description and pinned comment of the majority of the videos in this series and also on the Q&A page of the FilterPro website www.filterpro.co.uk where there is lots of other useful information.
@@MikeC-mf7dv Yes the lower the flow, the more the bacteria support will be skewed toward anaerobic and that effect will be enhanced with good quality media - even ceramic rings will support anaerobic bacteria in anaerobic conditions as it is simply a surface for bacteria to grow but the amount will still be minimal compared to good quality good porous media. Combine low flow with good quality media and let the nitrate reduction commence, lol
what would be a good filter for someone with a 55 gallon with plans to stock it heavily and eventually upgrade to a 150 gallon tank? the 55 is currently planted so that helps. but id like to find a good filter that will give me plenty of room to grow in the future. and hopefully last long enough to be around when i eventually do. ive been looking at an FX6 but id really appreciate hearing your thoughts.
If you're looking for a filter for a 150 us gallons tank it could take anything from an fx6 if it was light to normal stock to a unimax 700 for heavier stock.
@@pondguru The FX6 would not handle a heavy load? huh i didnt know that. ive always thought they were like the ultimate canister filter. And i cant say ive heard of the unimax. ill look that up. thanks for the input!
As far as putting your hands in water I can't see a problem but if you're injecting them or ingesting them internally I'm not sure what the effect would be (probably not good)
Ian Roughley yes that's what I thought as soon as I took it to bits and remarked on that while filming but I cut it out in case of offending anyone as there are so many snowflakes out there lol

The Dennerle scaper's flow HOB / canister filter is a really interesting design which offers a decent provision for both mechanical and biological filtration. Trays are really easy to set up with alternative media / foams and they fit together very securely to eliminate bypass.
The top media tray holds around 550g of Biogravel so is really suited to normally stocked tanks of around 60 litres (16 US gallons) or heavily stocked tanks of around 30 litres (8 US gallons) if you want to achieve a full cycle. If you are using this on a well planted tank you could achieve a full cycle in 100 litres+
A full cycle is completed by bacteria - the aerobic part of biological filtration which processes ammonia to nitrite and nitrite to nitrate followed by an anaerobic part which processes nitrate into soluble nitrogen which bubbles off to the atmosphere.
Therefore it requires a suitable amount of excellent quality filter media to be able to provide the environment for both aerobic AND anaerobic bacteria - that is what Biohome ultimate does perfectly but even with such good media there are limitations and we recommend the following amounts for different stocking scenarios:
(1 US Gallon = 3.8 litres)
(1kg = 2.2 lbs)
Average community tropical aquarium = 1kg per 100 litres
Average coldwater aquarium = 1kg - 1.5kg per 100 litres
Predator aquarium = 1.5kg - 2kg per 100 litres
Large cichlid aquarium = 1.5kg - 2kg per 100 litres
Malawi / Tanganyikan aquarium = 1.5kg - 2kg per 100 litres
Marine aquarium = 1.5kg - 2kg per 100 litres
Average mixed fish pond = 1kg per 200 litres
Average koi pond = 1kg per 150 litres
You may be disagreeing with the above figures but remember that they are for a FULL CYCLE not half a job - achieving 0 ammonia and 0 nitrite is quite easy since aerobic bacteria grows freely on any surface but the anaerobic bacteria responsible for COMPLETING the cycle needs more a specialized habitat.

Great little filter! fantastic for shrimp tanks.
Yes it would have been perfect for us when I had the shop as each shrimp tank could have been well planted with one of these on the back of each tank - cracking little filter and I was stoked to have this one sent up to feature in this series.
MARK'S AQUATICS I use the small oase external filter hang on back great filter too but this has more media
Could I use in a 11 gallon nano reef or salt water tank?
Bonus tip, if you run it as a canister system you can add a valve to your outflow tube to control flow :)
Just the job for fry tank, great video again .
Yes it would take some heavy feeding no problem and the inlet having a sponge over it makes it safe for fry or shrimps too.
That's exactly like the ultimate nature filter, I use the coarse pad and stuff that bottom section with poly fill, works great.
What a great little filter for a small fry tank. Another great pimp Richard

The bottom tray takes water in through the whole of the bottom so water is drawn in through the foams more or less equally. The same is true for the media tray.
@@pondguru Now I see the top of the media tray is solid other than the return to the pump. Nice design.
Very interesting little filter indeed, never seen anything quite like it.

Hi, love this video! Quick question, if the power ever goes out, will this filter start up again or is it like most HOB that needs water to be added to start up?

Using the Biohome Ultimate media... Can we achieve 'full cycle' including Nitratre removal when putting the Biohome into a high flow filters such as this or other high flow HOB filters? Or is it better to use Biohome only in low flow areas of filters or tanks to achieve Nitrate removal?
A low flow will encourage a more de-oxygenated water flow and therefore promote a greater proportion of anaerobic bacteria but the biohome will still support anaerobic bacteria in tiny pockets all through its structure in any flow, even a fast flowing highly oxygenated shower filter or fast flowing canister - recommended amounts to use are found in the video description and pinned comment of the majority of the videos in this series and also on the Q&A page of the FilterPro website www.filterpro.co.uk where there is lots of other useful information.
Great. I guess it would also make sense to use the 'low flow' lever that many HOB filters have. My Fluval HOB filter has this.
@@MikeC-mf7dv Yes the lower the flow, the more the bacteria support will be skewed toward anaerobic and that effect will be enhanced with good quality media - even ceramic rings will support anaerobic bacteria in anaerobic conditions as it is simply a surface for bacteria to grow but the amount will still be minimal compared to good quality good porous media. Combine low flow with good quality media and let the nitrate reduction commence, lol
I would be interested in seeing what you can do with the eheim pro 4 + 600 filter.
Yes if someone wants to send one then I'll do it no worries
good day Rich !! another superb pimp my filter episode !!
It was a real treat being able to take a look at this filter for sure.
Can anybody recommend a HOB I can hide a mini heater on please?
Thanks.
Check out the Tidal filters they might work out for you
Do a sunsun version with the prefilter canister too
Baran Demir he has done the sun sun canister, it on his "your filter is too small" video
Great video thanks for showing us.thats a cool hob filter
Yes, so much better than the travesties which rely on cartridges and replaceable parts - the only winner with those ones is the manufacturer.
I really enjoy your videos Richard 👍🏻
No worries, I'm glad you find them useful.
Hi Richard,
Enjoyed the video as always but may I ask how many litres you think this filter is suitable for?
Have a good evening.

Aengus Foley notes for that are in video description and pinned comment
what would be a good filter for someone with a 55 gallon with plans to stock it heavily and eventually upgrade to a 150 gallon tank? the 55 is currently planted so that helps. but id like to find a good filter that will give me plenty of room to grow in the future. and hopefully last long enough to be around when i eventually do. ive been looking at an FX6 but id really appreciate hearing your thoughts.
If you're looking for a filter for a 150 us gallons tank it could take anything from an fx6 if it was light to normal stock to a unimax 700 for heavier stock.
@@pondguru The FX6 would not handle a heavy load? huh i didnt know that. ive always thought they were like the ultimate canister filter. And i cant say ive heard of the unimax. ill look that up. thanks for the input!
Or do sponge then bio on the in. The sponge then bio on the out
are fish antibiotics safe for humans ?
As far as putting your hands in water I can't see a problem but if you're injecting them or ingesting them internally I'm not sure what the effect would be (probably not good)
Nobody has sent you a Fluval 70 yet Richard??
I've been waiting months to see that one...
HOB filters aren't very popular at all in the UK but I'm sure someone will have one to send somewhere as I think they are sold here as Aquaclear.
This look like a rebranded ista or shiruba mini canister filter.
Brill... I’ve had my eye on this
Yes it is a real hybrid which takes the useful parts of HOB and canister and uses them to good effect.
Speak it Danner - Luh :)
Denner-le - ist schliesslich ne deutsche Firma!

Oh come on!!! did no one else spot the “cartridge” filter bit looked like a feminine product? Great vid there Richard :)
Ian Roughley lol I did lol maxi pad
