I have a new 6 acre pond. After building I used 1 ton alum and 1/2 ton quick lime for a clarity of almost 28 inches. Then we got 5 inch rain that broke through the silt fences and undid all our good work and the clarity dropped to 8". Today we put in another 1ton alum and 1/2 T lime but the water clarity didn't change from the 8". The air temp was 40-50 degrees, I do not know the water temp. The alum has been stored under a tent for 5 months. There were a few chunks but mostly power. We mixed it like before in a 100gal tank before spraying. It was harder to get it in suspension. Does the water temp render it inactive or does it get old??
Thanks for any and all advice
