It’s been one year that I have been maintaining my pool.
I consistently had CYA above 90. So I’ve been keeping my FC around 10. Water is crystal clear and I only use liquid chlorine thanks to TFP.
My April reading was again CYA 90-100. However, in the past few months we have been experiencing very hot summer here in So. California. Almost every day or so I have to add chlorine to maintain my high FC. I figured it’s because of the sun exposure.
I did a CYA test after 3 months as I have been doing always and now it reads CYA 20-25. No drain.
I even bought a new CYA reagent thinking my original CYA reagent was old. Same result.
I did add 2 rounds of 18oz. PoolTec last month in hopes of not losing FC as fast but that didn’t work.
So what happened to my CYA? (Which I’m not complaining. Keeping high FC becomes very costly).
Should I be adding stabilizer now.
