I am actually doing it right now with a tank full of tilapia that Rex just delivered. Working like a charm, and the tilapia are really benefiting from the constant inflow of plankton.
I do the same thing. I have a real small (maybe 10x15') bait pond near
my main pond. I use a small solar panel and solar pump to keep water
flowing in all day long, and it siphons back into the main pond at night.
It really does work. A freak thing happened last year, and my pump stopped.
All the FHM went belly up.
