I built 3/4 acre pond 5 yrs ago now and so far all is well but the water always seems a bit cloudy and after talking to a local extension agent I was told it was suspended clay particles and recommended to spraying it with 50 lbs. of alum deluded with water and good sprayer so about this time last year i did just that and the results were great but this year it appears cloudy again.My question is 1st..can i apply Alum again this year and 2nd. where can i buy it in that amount ? Last year i found it all over the internet and this year i can only find sites selling 2 or 5 lb.bags.
This site is great and I've read a lot of the posts so I figured I'd turn to the experts for advice..Thanks again..Larry
