Backyard Aquaponics
A place to discuss aquaponics

Hi all. I am trying to get the ball rolling and I know I should be starting with a simple system but I really want to start with a small hybrid system that will fill my small space and provide more food that a 1 IBC setup. Again, thanks in advance for all the advise.

It seems like each time I think i have settled on a plan I think of something else that effects layout or system type. I will soon have a sketch to submit but wanted to ask some pros before finalizing my design.

So far I have sourced 2 330gal IBCs. I am planning a CHIFT PIST. I will stock hybrid Bluegill and hope to have a lean-to greenhouse before winter hits.


First, I really want a round FT and can't really justify the $500 pricetag of a fiberglass one to the wife. Closest thing I can find locally is a 6' dia. x 2' deep HDPE water trough. Are round FT's THAT beneficial to a smallish system? Will 2 SLO's do a sufficient job of removing the solids from an IBC FT at medium stocking density? The more I consider time and price, I lean more toward an IBC FT.

Second, I found some HDPE containers at a surplus store and was wondering about using them as DWC beds. Each half is approx. 5'x4'x2'deep (pic below). I thought about using them for media but would the corrugations in the bottoms be a issue? Will the corrugations be an issue if used for DWC beds?

Third, I want to dig these into the ground most of the way. Would it be okay to use one as the system sump? I would only grow lettuce in a raft and leave about a foot on the end vacant over the pump.

That is all for now. Criticism is welcome.

Weird, I was going to ask the same question, but searched for "DWC" and "hybrid" and this came up. So i'll have to watch this space.

Personally I think an IBC FT would be absolutely fine for what you want.

You may however run into some problems when trying to fit a bulkhead fitting to the bottom of those HDPE Containers for drainage due to the corrugations.

You might get away with using them for DWC Beds by fitting the bulkhead or Uniseal into the side down the bottom and then using a PVC elbow to connect the vertical standpipe.
