I am a newbie this year and am closing my AGP for the winter. However, I have run into 2 issues. One, I cannot get the fitting off of the return to add the plug. The fiting has 2 slots. Is there a special tool to remove this. I am worried about breaking the fitting.
The second issue is the pH level. I have shocked the pool (2 lbs shock and one bottle of liquid chlorine) and I added the algecide (Polyquat 60). However, my reading shows a low ph level. The Chlorine is at shock level and everything else looks good but the ph is low. Is this an issue for closing?
