Dr Joe said:I use computer UPS' and a small air pump split between every couple of tanks (check valves, check valves, check valves ! ). Had a homemade 12vdc generator w/ converter, let someone borrow it and somehow it got fried AND they ruined the engine trying to rev it higher to get voltage out of it ( of course it wasn't their fault ! ) ( never a borrower or lender be... I always wondered what my mother ment by that when I was little) so have to start over on that one.
If we could teach the fish to pull a leash then hook it to a wheel and have them swim in a circle to turn a little generator ( kind of a mouse in a exercise wheel thingie )![]()

Has anyone ever had to use their check valve, I have them on all my pumps, and I have never had that problem.
