I have some questions about my water chemistry.
Ordinarily I use bleach to sanitize my water; however, when school started back, I bought a bucket of tablets due to long late hours in my classroom. The water stayed clear, and I confess that I stopped testing it. We weren't swimming, and I was just waiting for a few free hours to close it. A friend is coming tomorrow to help close it, so I tested the water today. Wow! Ph was less than 6.8. TA was 10. FC was 3.
I've used the pool calculator and have been adding the recommended baking soda, borax, and bleach in small increments all day.
Ph is still less than 6.8, but I see a difference in the color, so I'm still adding Borax. TA is now up to 80. FC is at 15.
I checked CYA just now and oh my goodness. It was 90! I'm figuring it's those durn tablets, but I'm wondering if all the baking soda and borax might be suspended in the water and messing up my result?????
I'll check everything again in the morning. If the CYA is indeed correct, should I drain some now, or just wait until spring? Will this level damage anything over the winter?
Thanks for your help.
