Here is a better picture of the overflow.

Here is the backside of FT bulkheads as promised

Water inlet and airiation

And a added spray bar just for a little added insurance.

I don't think all of those pools have built in algacides/fungicides, but if it did, it could cause problems. You can order virgin liners or use a pond liner to be safe. You aren't running any air at all?

that style of bulkhead is so simple looking and I assume since I keep seeing them here they work. What are they called please and where did you find them.? Brian

oh I looked again those are the same as the bulkheads I use in my biodiesel processor except I use brass

Coach,
I did not see any comment about any algacides/fungicides on the packaging. Plus since it already has a nice layer of bio slime all over it. So if it was there it didn't work too well. I have also seen this pool used in greenwater Aquaponics on many videos before. As for right now I am not running any external air. At the moment there is no need for it. Unless of course the power goes out. It is on the list for a backup air system, just no money for it yet. I purposely used the venturi on the pump outlet. Which is placed about an inch above the bottom of the FT. To help "roll" the water to the surface. The pump outlet at the bottom also seems to help keep the solids on the bottom swept toward the SLO quite nicely. Given that the pool has a large surface area, and relatively shallow depth the amount of air being injected should be more than enough. The spray bar on top is pretty much overkill.

Boss,

I found the bulkheads on Amazon, from LaPonds. After reading a lot of reviews they seem to be a little thicker and longer than the ones I can source locally. They were even cheaper than the Uni-seal warehouse that is 20min from me.

How much does the pool hold about 6,000LT? Looks like you scored a deal at that price if it holds up for you and it should with shade and cover like that too.

Pond_Sucker,

Yeah I scored a deal and it was brand new. You just have to shop wise. I had mind shipped in from Indiana. Their prices were a lot cheaper because their swimming season is over. All the pool companies are trying to ditch this years inventory. Yeah it will hold a little over 1600gal (6000lt) But I do not have it filled to the top. So I can only guesstimate that it is holding approx. 1300 (4921) to 1400gal (5299lt) at the moment. Besides it being inside my screened porch you can also see that I have a heavy tarp that I use to shade the sunny side, and cover the pool; on cold nights. Which is the reason for the extra 2in pvc cross members.

The first pic is of the first barrel to hold my screen material. Second is of the first of 2 RFFs to be run in parallel between the FT and DWCs. So I can split the flow and lengthen the retention time so more particles can drop out. Without slowing the flow from the FT. Plus I would much rather avoid cleaning netting and shade cloth if possible. It's not lazy if it's designed in Hoping to be able to get to the point where I have to clean the netting and shade cloth monthly or less.

The blue barrel in the above pic is actually a 30gal drum cut in half and the lid missing. It is held in place by leftover aluminum crosspiece from the top of a IBC, and 2 zip ties. It is generally designed like the one in Ryan Chattersons backyard thread.

No trouble getting a seal on a round edge? I may have placed them too close to the bottom of a barrel which means no flex.
