Hi all! Thanks TFP for the welcome! It has been so windy here, the neighbors had 2 large trees cut down last week and my pool turned cloudy yesterday, ugh. pH & Alk were low-added 4lbs of baking soda, then pH & Alk went too high-shocked it last night w/1lb shock & swim, cleaned the brand new filter that had only been in 1 week. Pool store double checked my testing, said wait another 24 hours before using Alk up & pH up. I hope I'm on the right track. Thanks to all & happy swimming!
