why would I add hydrated lime before alum?? I'm not concerned with the PH, and would prefer to kill what is in there. I have read many times where folks had to do numerous applications of alum (ie: wasting money) because they did not put a strong enough dosage in the first time. Obviously, they were in fish sensitive conditions, which I am not.

The shallow water now, and the heat will probably kill what I have in there now, if I don't get some rain soon. But those dang channel cats can live in 6 inches of water...they are tough.
