Hi everyone...I'm new to the forum and was hoping someone might be able to help me out. My pool had been blue but very cloudy since last year. This year, I started off with the same cloudy water as soon as I opened my pool. I went to Namco and had my water tested and they said my alkaline was high so I was advised to use 2lbs PH decreaser for a 21'x41' above ground pool. The sales guy then said to put in 2lbs of shock. The next day I looked out and my pool is green and has been for 3 days. Hope someone can help.
Thanks in advance!
