How long does one application of dye last? I've got areas that are only 2 or 3 ft deep when the water is low, would dye prevent weeds and FA from growing in that shallow water?
I can tell you this. I use 1 gallon of AQ shade in my pond as it treats right at 1 acre 4 foot deep if I remember right. Anyway after the first treatment, if I want to the directions say to put a 12 oz can of dye in each month after that to help maintain.... AQ is a bit pricey but it does work... I just dump it in my air bubbles and let it do its thing. By next morning the entire pond is covered.
