I have an above ground 30 foot round vinyl pool with 52" walls. I'm in Louisiana with full sun all day. Pump & fountain runs continuously. I've already stopped using the chlorine pucks so the cya won't climb anymore. We had an enormous amount of rain last week and I haven't added any chemical since then, but did have to drain water several times and I vacuumed out the mustard colored algae. Any other background info needed? I tested using the K-2006 FAS-DPD kit and can't figure out the included wheel chart.

Ph 7.4
TA 60
FC 4.4
CC 0
CYA 88
Calcium 60

How much baking soda should I add? And what will that do to my ph? How much borax should I add?

At what level do I need keep the chlorine since my cya is so high? And was the algae caused by the rain or my cya level? I didn't notice it before the rain.

Thanks for your help!
