Hello again everyone. happy Halloween. After have an initial honymoon period with BBB I am now starting to have cloudiness problems. I am in a very remote area and I fill my pool from a hand dug well. The water going in seems to have a very fine silt which my sand filter cannot seem to get out. Coagulants seem to be the thing that worked before I embarked on the BBB method. Is it ok to use them again. The problem is they put a weird floating stuff in the water that takes a little time to filter out. Also the vacuuming to waste after using them is very water intensive. In pool school it has an article about adding DE to my sand. Is that an option? Also, has anyone ever used the glass replacement for sand (http://www.ecosmarte.com/hydrox.html) that ecosmarte sells. Any ideas would be greatly appreciated, i'm getting weary of cloudy water.
