My screened porch/deck is under contruction so I've left my loop-loc security cover on the whole season so far. The pump & SWG (35%) are running 4hrs a day. Water is clear, but some stuff on the bottom since I only vacuumed once when I opened the pool in May (then put the cover back on)
CYA 50 (added 4 pounds)
Salt 2900 (added 160 pounds to maintain)
I'm concerned with the calcium harness. We've had a lot of rain and I added 11 pounds of "hardness" when I opened the pool but it's still dropping. What about the upward Ph shift? FC is still slowly working its way down from the opening SLAM process. I could drop the SWG % down a bit, but when the cover comes off soon, the sun will start working on that chlorine.
