Can anybody help? I am not sure where to go from here. Last night I took my Chlorine level up to 20. I checked every three hours today and added bleach every time to keep my chlorine level above 20. (It seemed to drop about 1ppm every 3 hours). This evening though there was a thin layer of algea over the entire bottom. It vacuumed up real easy (I vacuumed to waste) but I am not sure where I go from here. I am waiting on the pool to fill back up to its normal level, then I am going to do another test.

Any suggestions would be greatly appreciated.

Thanks

Tim
