We have had our pool for 3 years now. We started off using Baquacil which seemed to work ok but was rather expensive. Just recently, we were told (by our pool store rep) that E-Z Pool was the way to go. We were having a bad problem with a cloudy pool so we made the switch. We were able to get the pool clear for about 2 weeks and now I have a algae problem. They (the pool store) had me add shock to clear the pool which I have done but the water is still green. I can see the bottom if I stand right over the edge. I vacuumed the pool yesterday and then cleaned the filter which did not appear to be too filthy so I don't believe I have any real buildup on the bottom. The water just has a green tint to it. I have been reading posts on this site and reading articles in the Pool School and feel like it is time that I take matters into my own hands.
I do not have a good test kit (yet) so I have no idea what my CYA level is. My test strips show that the FC level is ok but who knows what level ok is. So.. here are my questions. Do I need to determine my CYA level before I start any sort of treatment? I figure that I need to add bleach to start fighting this problem but I have not been able to find anywhere that discusses how much bleach should be added to get to shock level. I bought 2 gallons of bleach but how much should I use?
I would appreciate any pointers that anyone can give. I am hoping to have a clear pool in a couple of weeks for my son's birthday party so I am anxious to get started.
