Update. Well, I have read defeating algae...and I feel like I am on a mission! I must conquer algae. I am taking the day tomorrow to fight. Tonight I went over to check on the pool, and was happy that there was some change at least. I could see the bottom of the shallow end. It looked pretty good, except for a little dead brown algae on the bottom. In the deep, I can make out a large area of darker scary swamp. So I hooked up the vacuum and vacummed the shallow which went beautifully. I switched to vac to waste, and put the pole in the swamp end. I was excited to see my backwash hose begin to dump thick green soup. With a smell like possibly there is a dead animal down there. )or maybe the previous owner didnt really move at all, and someone disposed of him down there). I mean it was awful!!!! But then all the sudden, I the vac hose got stuck. I turned off the pump and when I got the vac up, the attaching end of the vac had broken/cracked off. The head was old and poss dry roughted. So I turned my filter back on and called it a day. I went to pool store and bought enough shock that should in normal circums last me 2 years and Ch tabs. Also bought a new super duty vac head. Tomorrows plan is to return and vac to waste as much stinky junk as poss. Could my pool every turn clear with all that muck in there? Was my pool guy really pulling my leg when he said we would be normal in 2 more days? He actually told me Sat... that my kids could get in if they wanted. After smelling the "dead" smell, I want to put him in the end of that pool. The only other question I have is that all the abbrev in the link sent above? Is there a key somewhere?
