Hi Everyone and Happy Spring. Well, I am getting ready to open my pool next Mon and I peeked under the cover yesterday... Well, I have a green slimy swamp. Not really sure what happened over the winter but there you have it. Only my second time opening my pool and last time was easy, no algea. My question is what do I do first???? Not sure how to deal with this one?? ( I will be using BBB).
