I used same pallets for my wetland filter and I worked really well
I thought I convinced myself that the void space under the rocks was not needed if I have enough pipe space leading the sludge back to the cleanout if properly pitched downhill. After reading these comments I am questioning myself and think the void space under the filter rocks is needed. Thanks folks for the convo and video here!
I think using the pallets is a really good idea because as the water comes through it will perchlorate through all the bottom of the gravel and not just take the path of least resistance in only a few spots along the centipede. You want that slow up flow as even as possible as it will create the right conditions for denitrification bacteria to remove your nitrates. And cleaning will probably be much easier to collect the solids by back flushing the gravel down into the void space without it getting trapped in the gravel so it can be sucked out through the snorkel. Cheers!
I love aquascape products. But man" are there far too expensive! This what you've made here, probably works just as good for a fraction of the price. Thanks for the tips 👍 I think I'm gonna do that very thing !
i did this. i stacked 3 layers of pallets total height 45cm. plasticpallets hold up to 2000kg. matrix box were way to expensive.
my bog filter has a flat bottom. 45cm pallet dpeth. 15cm large stones, 15cm 2/3 gravel, 30-40cm peagravel.water depth on surface of peagravel 20cm +/-. total surface area 19sqm, rubning 6000l an hour pump.
it polishes the water up nicely.
Thanks for sharing! Glad to hear it worked out for you. The pallets I've found here come rated for different levels of duty. I think 2000kg would be a stretch for the "light duty" pallets I have. Maybe as long as the load is spread over the entire surface. Did you get the more heavy duty ones?
@@TylerTervooren 2000kg rating i believe is more than sufficient. i doubt that the layers of stone, gravel dan pea gravel combined is more than 2 ton per square meter. i didnt go with the heavier duty pallets, just what was available to do the job.
maybe some one can correct me if i am wrong.
The pallets are a clever idea..... I've never thought of that!
However, it's not enough. The purpose of the Aquablox is to both diffuse the water throughout the wetland, to slow the water, AND provide for a settlement area for solid debris. If I were you, I'd add 4 more layers of those pallets before adding the sedimentary layers of rocks and gravel.
Additionally, you will need stronger support in the middle of the pallet to prevent them from collapsing. What do you think the best DIY hack would be? I have my ideas..... ;)
Overall...... I like the ingenuity of the design and the use of the corrugated pipe. However, please be advised that the flow of water is best when flowing into the wetland, horizontal from the end of the pipe towards the snorkel. This allows the water to slow down.
Velocity is everything.
Good luck with your project, I've subscribed and rang the bell so I can follow your progress :)
Wow. Thrilled to get feedback from one of the best in the business. I came to the same conclusion as you about the plastic pallets. I'm going to stack firewood on them instead. They make significantly stronger ones, but then you're approaching the price of aquablox, so might as well just use the "good stuff."
I bought a few aquablox, some milk crates, and these pallets and have been doing a carefully controlled lab study of their strength by jumping furiously up and down on them. So far, the aquablox are winning by a large margin.
The milk crates stacked upside down are pretty strong since they are small and continuously supported along their edges. I think they'll do okay in a bog where a couple thousand pounds of dead load from gravel are being imposed on them and very little live load.
One other thought I had was to just buy some more of the corrugated pipe and slice it up like my DIY centipede and lay it on top. It's probably even stronger than the aquablox as it's designed to be driven over by log trucks and heavy equipment.
Curious to hear what you think. If I were doing what you do-building luxury ponds for clients-I would never even consider these DIY hacks. I'd buy the purpose-built materials and never give it a second thought.
That's a good call on how the water enters the centipede, too. Thinking I'll stick a long sweep elbow on the end of the pvc to make sure it enters horizontally.
Great conversation and comments as I’m contemplating adding bog filter to my existing waterfall and pond. In this particular build, were you just dropping the water into the bottom of the bog? The horizontal suggestion would have you add an elbow where you were dropping and then extending the water drop into the corrugated pipe- am I visualizing that correctly? Does it matter how far into the pipe you run the water?
@@n173021x I was planning to drill a hole in the top of the centipede and just drop the 3" line into it, but modifying the plan per Carl's suggestion to add an elbow and have the output horizontal. That will allow the water to enter the centipede with less splashing/spraying which will help any solids in that water settle out instead of getting carried up into the gravel.
I don't think it matters too much how far you run your input pipe horizontally as long as the centipede is properly sloped towards the snorkel and the water is flowing into the centipede and not splashing out around the side of it.
Yes pallets and milk crates are the original aquablox!
nice update buddy
Love it mate. Can’t wait to see the finished product.
Tyler, when will you show your next segment? Nicely done!
Check out the wetland filter play list in the video description. I just posted an update the other day. The location has moved and the design has changed. A video of the full build with all the details will come once it's totally complete.
0:11 Tyler any new updates on the pond?
this is brilliant...here's some pricing from Aquascape in Aus.. Centipede -$1000 ,Snorkle - $1300 Aqua blocks $57 each..complete Wetlands filter setup -$4730...without aquablocks I reckon your setup would be under $100....would love a follow-up to see how it operates
Thanks Brad. I do have an update planned. I’ve changed the design quite a bit since this video. Will update with the final design and costs. Subscribe to the channel and follow the garden pond playlist to make sure you see it.
The culvert piping is not cheap in The US, but I believe you have a lot more options available in AUS that could work well.
Couple of questions... 1. How did you join the centipede to the snorkle and 2. How did you join the pump discharge to the centipede?
Hi, I'm building a fish pond and right now I'm dealing with a problem with the wetland filter. I want to DIY it and I need some advice. Can I use fresh quarry stone for the bottom two layers of stones or is it better to just use river gravel?
Question: Would you use this system (or a waterfall & skimmer filtration system) for a pond that is part of a sunken garden where I want the pond to "leak" to water the bog plants? (I posted this in more detail on a video that suggests allowing runoff to seep into the ground.) Thank you for the money-saving ideas.
Tyler thanks so much for making this video! What is the thickness of the rubber liner you are using for your wetlands filter and pond? Is it better to have the wetlands filter before it goes into the pond or after?
Hey Gerry. I'm actually not using a rubber liner. I am using a 30 mil RPE liner. They are more puncture resistant and lighter weight than 45 mil EPDM liners, but they are a bit harder to work with.
Depending on how you design your wetland, you can place it anywhere. Above the pond usually makes the most sense for an active wetland filter, but there are lots of ways to modify. What are you thinking for yours?
Where did you get the pipe? I'm having a real hard time finding double walled culvert pipe..
I live in the Pacific NW, and I got mine from a local logging supply store that sells road building material. Most landscaping supply houses around here carry it, too, but at much higher prices, and only in 20' sticks.
I think you'd be okay using single wall if you can find it in big enough diameter. You'd just have to accept that the bottom of the corrugations would clog up and probably never come unclogged. Not that big of a deal, in my mind.
A year later. Any regrets?
hi tyler great ideas! im building something similiar, wanted to ask you think i can go with a non corrugated pipe? i have some in my back yard, or do i neceserally need a corrugated?
Definitely not required to use corrugated pipe. As long as what you have is big enough and strong enough after cutting the perforations, it doesn't matter what the profile of the outside of the pipe is.
Where did you get the material to make the centipede/ snorkel?
I found them most reasonably priced at a logging supply store, but you should be able to get them at any major plumbing supply house like Ferguson or irrigation supply house like Ewing.
@@TylerTervooren thanks for the response.
Have a good weekend!
Can't wait for the update/next videos.
How big is your POND ? We are Building a HUGE organic swim pond ... 60X40 foot and we are trying to decide sizing for wetland filter
Hi Nichole. I need to film an update as I've actually changed the layout of the pond since filming this. The pond itself is about 18x30. Total wetland area typically recommended to be somewhere between 15-30% of surface area of pond. Swim pond needs better filtration than typical garden pond since humans will use it. Performance-wise, you can never have a filter that's too big, but you can definitely have one that's too small.
I will be at about 30% split between two filters. One is a traditional bog/wetland filter that will waterfall back into the pond. The other is an upflow under gravel filter. Same idea as wetland, but is at bottom of pond.
@@TylerTervooren YES ! We went super BIG with 2 Xtra Large Bog Filters as well as 2 skimmers
With respect , am a filter guy , plastic is cheap and inefficient , long term . Stainless steel wedge wire is the best ! Buy now , save later .
