We are still fairly new at the whole pool thing...it is IG and about 25000 gallons. It was very dark green (we didnt cover it at end of summer...still learning) we shocked it and now its a nice blue but very cloudy. We took a sample to the pool store and they said add stabilizer and chlorine and let sit 72 hours...today is the 72 hr mark...still cloudy???? And reading 0 chlorine and low stabilizer. We live in the country and have very hard water...been a very wet summer too....any ideas?
