Hey Esshup he says above that someone treated the whole pond over the month of august and then in October he had the fish kill. So about a month went by?? Maybe not a D.O. crash??? If his water was fine? It sure sounds like a D.O. issue. No telling for sure!


Could be a month, could be almost 3 months......

With windmills, the variables are tremendous. Plus with an air stone, when was it cleaned last? As time goes on, the bubbles get larger and fewer..... IIRC, I think it's recommended that you clean even the membrane type diffusers yearly. Those are the easiest. Pull 'em up, scrub them off, drop them back down. IIRC I think the air stones need an acid bath to clean them up. (Muratic Acid)
