So it looks like I have some problems, I couldn't get the CH test to turn blue so not sure what that level really was but draining the water to lower the CYA should fix the CH, too. I did not test the CYA last year so I'm not surprised it was high. I've been fighting a small algae problem which is no surprise since I've been keeping the FC around 2 all last summer. I've been using Omni 3" tabs since the pool was built 3 1/2 yrs ago so surprised to see the CYA so high, does that seem normal?
I'll have to search here how to drain the pool or call my builder, the calculator says I need to drain 60%. Dumb question - can I use the drained water to water my yard or do I just run it down the storm drain? Not sure if the chlorine would be bad for the yard.
The calculator says to add 224 oz of bleach now to get the FC level up. Would it be "close enough" for now just to add a 182 oz jug?
