I know this is an old topic but, I have a pond that is approx 11,200 sq. ft. on the surface and about a 5 ft av. depth. I did a jar test with 1 gal. of water and 1 tbls cleared it in about 8 hours. How much alum would be needed? Also, would applying it from a small boat by dumping it in the motor wash work?
It's true hard work never killed anybody, but I figure, why take the chance? Ronald Reagan _______________ The good Brian
