That's basically the idea Festae Guy, although I'm not plumbing the inlet because I like using the watering halo, it would work either way you want it but yes it will definately help filtration.. the plants feed on the fish waste, in turn it helps to filter the water as well as the expanded clay eventually building up its own bacteria
the 40mm outlet is sufficient for a canister, it would even handle 2 quite comfortably but 1 will give me the right flow for watering
In the last day I've decided that I might go a little bigger on the tub, something a bit narrower and longer so I can eventually add some more plants, I might ditch the halo and use a long spray bar.. I haven't decided yet
the important part is getting the shelf solid on the wall.. It's not going to be super heavy but I don't want to take any chances..
Will be interesting to see how you go bro!
I know right! I'm kinda stealing the idea partially from vertical gardening, a little from hydroponics and a portion of aquaponics. Pics to come soon!
