Sorry about that. I'm talking about my pool. I'm losing CL during day only. I have the items listed above, tabs, stabilizer, and shock. I switched to BBB and I have this leftover. I suspect I have no stabilizer due to the daytime CL loss and the test strips stating it’s zero. I’m hesitant to use tab, stabilizer, and shock that I already have. I’m hesitant because I don’t trust the strips. I cannot get a good cya reading because I ran out of the Taylor Kit, r0013. I ordered more but it has not been delivered yet. The last Taylor cya reading was 70. This was 2-3 weeks ago. The strips are telling me there is no cya, which would make sense. I don’t know if my stabilizer can drop that much, so I am skeptical of the strips. If you tell me, cya can drop that fast, I need to add stabilizer. Should I use what I have on hand or go buy bromines?
