This was my second summer for bacquacil and I've had nothing but trouble the entire summer. I've dumped hundreds of $'s in chemicals and have had green water all summer long. Not until about a month ago was the algae noticable. I kept being told at the pool store that it was just green water, no really good explanation. My dilemma is this. I'm wanting to close the pool and just forget the whole thing till next summer. Do I need to get all the algae completely eliminated before closing it up and if so how do I do this since nothing so far has worked that the bacquacil dealers have sold me. I will not be using bacquacil next summer. Please help, tired and frustrated.
