I did my first opening yesterday. I left the loop lock cover on because of the impending oak tree pollen bloom that's due, but I wanted to get the water balanced and filtering.
Temp 56 deg
Since I need calcium anyway, and I have half a bucket of 73% hypo, I'm using that before switching back to bleach. I plan to put in 150 pounds of salt when I can find some. I was not going to up the cya yet since the pool is covered and it gives me a lower slam level.
I put in 36oz of 73%hypo which pool math says that'll give me 10 free chlorine. I did that last night. This morning it's back to zero. There's quite a bit of leaves and junk that got under the edges of the cover through the winter. I did another 36oz of chlorine just this morning. I can check it every 2 hours today since I'm off from work.
How's the plan sound? Should I leave the ph at 7.5 or dry and drop it to 7.2? I was going to wait until after slam.
