Here's what it looked like at 11:30 this morning. It tested great, nothing needed at all. We haven't seen any rain in quite a while, and it's been warm, so the lawn is starting to get brown tips. Therefore, out of the pool and onto the lawn. Then refill. I sucked the hot tub dry then pulled the pool down as low as I dared. Probably 2000 gallons. Which should do wonders for the high CH and slightly high CYA.
But now I have to start all over getting pH, TA, and FC just right.
