Well I was thinking today because I have two powerhead/waterpumps set up atm just pumping out water in the paludarium and it gives it a pretty strong current. It looks really neat so I was thinking......
I could mount my TV on the wall above my dresser. Alon the entire length of the dresser I could have I really long but shallow tank. About 1 ft tall maybe alittle more and about 5' 5" long and 15-18" wide. I would have 5 of these powerheads going.

It would simulate a very strong current/rapids. I would use large pieces of pvc pipe(10" diameter) as the container for the water leading to a pool. It would be Rapids to calmer water. I will try to illustrate as best as I can. I cant really type out water I mean so I will try to do a paint version.
I basically want to give it a rough rapids looks and then end in a semi calm pool. Just an idea. Not so much for fish but technicality, the fun of building it and it would look neat.
