I am working on a 225 Cichlid set up, planning on an overstocked African population. Have seen Under gravel jets so thought i would try my own. Instead of powerheads, I am planning to use the return from my canister filters to push the water from the bottom to the top of the 30" tank. After some trial and error (s) Decided to try 3 filters, each running 4 jets with the optional spray bar.
Seems to generate decent current.
Didn't like the look of the pvc
against the blue background so thought i would paint the down tube, blue. Started thinking that paint in the tank might not be a good idea.
I guess i need some Aquarium Advice.
