I took my bio pellets off line a few months ago on my frag system. I've over fed and have just let it go to see how nasty i could make it (within reason naturally) raisind nitrates, etc. Haven't changed the water or done anything. Got hairalgae everywhere, nitirates off the charts. I put the biopellets back online yesterday not gonna change water either and am gonna see what happens? Coral frags are irritated but still ok (i cant kill corals lol) cant wait to see what happens. Anybody ever done this?
