obviously there is much more experience here in river tanks than in TPT so i'm sure i will get better adivce and thoughts here.

I've been dreaming up a River tank (or something similar) in my mind since i first laid eyes on a Hillstream loach. My plan is to take a 40B and make my tank. what i was originally thinking is to take a piece of slate or flagstone, and have it cut in into a s shaped river bed, and then to lay it from front to back in the tank, and surround it with sand. then take a canister filter for 175g tank and run the flow from that onto the riverbed. and then use a canister filter for 55g to do the actual filtration and have that run from left to right across the tank. i have seen the plans for the river flow that was created here and i am planning on doing a modified version of that with the canister.
this is will be a multi-species tank that include the loachs, bamboo and vampire shrimp, rummy nose tetras, corys, and a family of double red agazzi cichlids. (this is basically upgrading a already running tank.)
