    I’ve used UGF driven by power heads for 30 years with great success. All other filters took methods caused issues such as leaks and other crashes. This is a great piece of education for new aquarists.

    if you wanna stop clogging in those air stones take a pin or tack and punch small holes in it. it'll work fantastic for years and not plug up at all. sometimes it's easier to heat the pin or tack with a lighter and melt a pin hole.
    it's been my go to hack for 20 years.

    Great video and somewhat surprising finding someone as young as you are educating your viewers on the many benefits of anoxic filtration. Many of today's aquarists simply do not know how to achieve a full cycle, much less even knowing what a full cycle is. Happy to know you're doing your part in educating those in search of the perfect aquatic biotope. You certainly earned my subscription. Keep on, keeping on.

    Thanks for the video.Dr. Novak is also using this method. I think, I will use this filter to my other tanks. I tried father fish method but I didn't follow some of his instructions like the ingredients for the soil. I used my own compost and backyard soil. I don't have trust on potting soil from online shopping. I still do water change but twice a month. My 2 year old danios are still alive and my elodea plants are still thriving. I have hygrophilla stricta too.

    You will find that using UGF's is that your plants will thrive on their own without having to use root tabs or anything to that nature, I had a tank for years in the living room with UGF's I was forever trimming plants to stop overgrowth, then my wife started to complain about the bubble noise so I changed over to a canister filter, ran them both till the canister was cycled then slowly turned down the air on the ugf's till the canister took over. My plants started to change colour and slowly died one by one, plants that had thived for years all slowly died off, no trimming needed. I now have the UGF's working again as the boss decided to put up with the bubble noise in order to get the beautiful plants back again. Just got my first flower coming out on an anubious after replanting with the UGFs running again.
    Just think about things, how many lakes and rivers run canister filters to keep the water nice and clear, exactly, none(other than sewage plants) so to you diehard canister people which system is closer to natural nature?
    I put down the comercial sector being to blame for the hype about other types of filter, if they can sell you a canister filter you need to go back and constantly buy new filter medium etc so they keep your buisness, the other way is they can sell you a far cheaper UGF tray and end of story to their earnings, so it makes sense for them to push you hevialy towards buying expensive alternative filters, you could buy a lot of fish, plants and food for what even a modest canister filter will set you back.

    @BM-fw4xt 9 месяцев назад +1

    There is some good information here to get people thinking about UF. There are a few things to keep in mind though. When he says sand. He actually means the gravel substrate. Sand will not work because it will fill in the UG filter. Essentially the gravel is your filter media. Just like any filter. The water flows through to carry oxygen to the beneficial bacteria. If the gravel bed gets to clogged. Your filter basically slows to a stop. This is why you still have to vacuum the substrate to keep the water flow moving. The undergravel filter was never meant to be operated with a excessively deep substrate. Air driven UGF can't operate at full potential with mulm clogged gravel. Visually seeing mulm doesn't equate to visually seeing nitrate. Used all kinds of filters since the seventies when I was a kid. Starting with undergravel filters. Still use some of these. Happy to see this video. Takes me back to great days an d memories. Thank you.

    Ok, Decades ago I was really into the hobby and Under gravel was what you used back then. I ran it with powerheads and a couple small HOBs to pull floating waste out of the water before the under gravel pulled it down. I have been looking at starting up a 55 again and this slow building system is interesting to me. The reason is I don't have time to be messing with an aquarium every weekend and I always loved making the tank look like a slice of nature. The fish were the problem for me dealing with water changes and vacuuming, testing and losing fish would always ware me down. Thinking back, I realize where I was going wrong, I was cleaning to hard and killing the good bacteria so I Would have crashes and that was why I lost fish. Now I have been looking at the plenum filters and thinking how that muck layer I was constantly trying to keep away was actually what needed to be there.
    My new thoughts on this are a hybrid plenum/under gravel system. Run two medium HOBs Aqua Clear 50 (200 GHP each) and the under-gravel plates with NO air stones in short lift tubes. The reason I think this would work is where the HOBs dump the water will work its way through the gravel and under the plates and create slow flow zones with low oxygen for the other bacteria (anoxic) to finish the cycle.

    30 years ago when I got into fish keeping that was the way to go. a power hwad was about all you needed to boost it. hang on back filters were a nice add on for top surface movement. as a kid I had a 30 gallon with an air powered filter that had charcoal and cotton fibers that worked great too. we've gone for high tech..high priced stuff for the last 30 years especially in the last 20 with canisters becoming hugely popular in the late 90s
    underground is what I planned on using in combo with a canister bow front 100 gal I got last year.

      @@davcar872 mate it's just an undergravel filter with an air pump. Loads of fast growing plants. It's a 300 liter tank 4ft long. It can be thrown out of balance if I feed to heavy though. I do water changes though coz I worry maybe the waters getting low on some kind of mineral or something. I usually change about 40 liters every 2 weeks or so.
      I had a stronger cycle with canister though I could feed as heavy as I wanted and I went months without changing any water once. The water was no where as clear with canister though and cleaning the can was a nightmare. Using a can though there was much less oxygen in the water I kept having to make sure the spray was in the right place.
      Depends what you want. Canister much better cycle but less oxygen and can run into the fish all at the top gasping for air. Ugf much clearer water but you do have to be careful with overfeeding.

    I have been experimenting with DSB and DSB with plenum for almost 4 years now..
    So what you are planning to do, about increasing thickness of gravel, or even changing gravel to something finer to further reduce flow ( slower the flow, more chance of it being anaerobic right?)

    I am interested in UGF because of the huge surface area of the substrate. My first tank had one. I also like the idea of delivering the nitrogen to the substrate for the plants. I'm somewhat skeptical of the anoxic filtration- I think that the plants are doing most of the work in these tanks. I had always heard that UGF's are bad for planted tanks. I guess that's not the case!

    Recently found your channel and really enjoying the content. I fullt invested in dirted deepsand substrates with around 20 tanks setup that way however I've never used an undergravel filter and am tempted to try one sometime to compare the differences.
    With dirted deepsand, I've go by the rule of thumb that approx 2 inches of pool filter sand is needed to deplete oxygen sufficiently to create an anaerobic environment in the substrate below that, which would ideallybe another couple inches atleast. But that is based on no 'forced ' water flow into the substrate, so I'd guess that with the increased water flow into the substrate from the undergravel filter that the substrate would need to be substantially thicker. However since I haven't experimented with this yet, it'll be interesting to watch this project develop in your channel.

      @@crispy6532 since commenting, I've been running 4 ugf's with pool filter sand as a cap and 1 experimental ugf which is under a dirted deepsand substrate. I like the ugf, but they haven't provided as much stability for water perimeters as a dirted deepsand bed. After a year of experimenting with ugf, I'll keep the current one's running but all future tanks will be dirted deepsand along with a sponge or matten filter. One specific use I prefer ugf for is as a quarentine tank. It seems that a well seeded ugf does a wonderful job of mitigating pathogens etc on new or stressed fish. Personally I'm skeptical of the idea that any of our substrates are achieving denitrification through the use of anoxic conditions (and bacteria). Even the dirted deepsand substrates. Suspect instead that nitrates are being consumed through assimilatory denitrification in the substrate and through vigorous plant growth.

    Malik, you seem to be very experienced with undergravel filters, not to mention knowledgeable, as well so I would really like to ask for your opinion on the use of UGF (as an anoxic filter) with sensitive blackwater species.
    I'm planning to setup a 4' blackwater "hodge-podge" tank which will house species from the wild (which I'll catch) e.g. 6 banded barb, chocolate gourami, etc, so here is my query. Would it be ok were I to *lightly* vacuum the gravel & leave the bottom 1" or so anoxic? You see, an UGF can harness the aquarium substrate's potential as a bio-filter which becomes especially important since it has been studied that low pH reduces filter bacteria efficiency. The problem here is that blackwater fish are very sensitive to (usually heterotrophic) bacteria build-up & that necessitates removal of excess mulm.
    What do you think, bro? Periodic light vacuuming of the substrate? Or, only vacuum the substrate once the system has stabilized? Thank you so much for any advice, in advance! 🙏

    • @AquaMalik
      @AquaMalik  3 года назад +1

      so personally I would go with an active substrate and hang on the back filters or other type of easy to maintain filters for your specific set up as there are several issues arising from the low ph as well as increases in decaying vegetation and biological matter which can accumulate in a black water set up ..light vacuuming of gravel with undergravel filters is ok but personally I dont do any vacuuming or any maintenance for that matter with this tanks.. only top ups and water changes every 3 to 4 months maybe!

    • @AquaMalik
      @AquaMalik  4 года назад +1

      Dan Heider it’s pea gravel as bottom layer and top two inches is fluorite Red! Any general aquarium substrate should work - except the ph buffering higher end ones like fluval stratum and ADA - those will break down over time so anything but those kinds - Best of luck 🍻

    I really hate cleaning my substrates.. when fishfoods and fish poops went to the bottom and lies on the substrates my filter can't suck those dirts and I have to keep cleaning it (btw my powerhead is very powerful)... does this undergravel filter fix this problem? Does it remove the dirts from the gravel?

    • @AquaMalik
      @AquaMalik  3 года назад

      So the trick is not to overfeed - and yes once u have a properly established under gravel filter there will be no need to gravel vacuum as the poop turns on to food for the bacteria that gets established in the u g filter

    Do the plants grow well on these gravels?
    I am planning to use my older UGF on a smaller tank (40x20x20 cms) for my son for a betta and a few tetras but wanted to have it a planted tank. how much gravel should be used over the UGF plates? and I might just have 1 pipe connected with the air pump to reduce the movement of water and a submersible light. Thanks in Advance!

    • @AquaMalik

    • @Aqua_Gino
      @Aqua_Gino 4 года назад

      There is somewhat more substrate compaction with UGFs that pull water through the substrate from top to bottom. That could create problems in some cases. However, in systems that push the water up from underneath the substrate (fed by another filter taking out any particles present) plants are thought to actually do better than they normally would, because their roots are allowed to "breathe" more. :)

    • @davcar872
      @davcar872 3 года назад

      @@Aqua_Gino I am sorry, as I have to disagree with your statement. Yes, you are correct in that water is pulled through the substrate but with the minimalist of flow as required for anaerobic denitrification to occur, substrate compaction is of no concern. Compaction has more to do with the porosity of your media, with sand being the least porous, rather than the use of a UGF. Rooted plants need a somewhat compact or heavy substrate for proper anchoring as they require nutrients deep in the substrate to keep from melting. Rhizome plants such as Java Fern and Anubias are probably what you are referring to when you state their roots need to breathe. They don't draw any nutrients from the substrate because it is a water column feeder plant that draws nutrients through its leaves. We all strive to achieve the perfect ecosystem with no single way the only way. So if what you do works, keep on keeping on.

      as the tank gets larger you might need to get a big canister filter or a sump to handle the potential bio load..

    Undergravel filter is too underappreciated! It works REALLY well in my experience, and it emulates how nitrogen cycle are done in the natural river streams.
    Fish tanks are designed to be balanced and sustainable like the nature, and undergravel filter is the MOST sustainable and low maintenance biofilter.

      @howardhewitt1797 4 года назад +1

      Apparently it's not without oxygen (annerobic) but low levels of oxygen in the deep gravel (anoxic) that causes the process of nitrate elimination, the magic happens when the bacterior use the oxygen within the nitrate molecule to do their business, the nitrogen gas is then liberated completing the nitrogen cycle.
