I was late in covering my above ground bestway pool. With all of the rain and leaves my pool turn green. I brought hth green to blue treatment not knowing that it's not for an above pool. It didn't say that on the packaging. I can not get this stuff out of my pool. I'm looking for help to see how I can filter it out. If I drain it will it be bad for the environment? Is their anything that I can put in the pool to help dilute this brownish foaming stuff? Please help.
