Here's my 125gal African cichlid tank that I'm experimenting circulation pumps on, and in the above picture I have two hydor 1500's catty-corner creating a swirling motion and agitating the surface for oxygenating the water...
...however while the fish are rather undisturbed, I'm finding I have a deadspot behind my rocks where poop collects. Any recommendations on moving poo from behind rocks without pissing my fish off?
