Thx. instructions on bottle say rebalance water in 24 hr and change out cartridges in 48. Is it okay to use auto cover at this point to help protect from algae. I ordered the polyquat 60. It doesn't arrive until tomorrow. We had a lot of rain yesterday. I took advantage of it and that's what made the final depletion of chlorine
That's correct. You have no multiport valve or recirculate position.
