Just curious if this is common. I have my SWG off (well 1%). I wanted to know my daily FC loss so I could set my SWG accordingly going forward. Yes I realize I can just shut it off soon due to cooler water temp and just use LC. I tested before pump came on today at 8:00 am and got 7.5 ppm. I then tested at 6:00 pm when pump was off and got 7.5 ppm. No loss of FC. Water temp is 68 deg and my CYA is 70. I’m confident of the CYA as tested by tf-100. Anyways just curious with colder water if it is common to lose no FC in day. I plan on doing same tomorrow. I’d also add overcast all day today with sun going in and out.
