Chlorine Tablets for Pentair Rainbow Chlorinator

[kingadriann]

I have an in-ground pool. My water is super clear, but when I test the water, everything but the CYA level is high.

I use Regal brand stabilized 3" tablets and put a stack in my chlorinator.

Can anybody suggest what I should do to maintain good CYA level without having to drain the pool?

Any recommendation is appreciated.

I will attach picture of my pool water.

Thank you in advance.

The use of Trichlor for daily maintenance is not sustainable.

You can add liquid chlorine every day to raise your FC to target range based on your CYA using the FC/CYA Levels
Or you can install a SaltWater Chlorine Generator that will create the chlorine your pool needs every day.
