New-to-me pool owner, came here and did the following: bought a K-2006 test kit, set up a spreadsheet, tested my water basically every other day for the last week.
Here's where I'm at after a few days:
FC pH CC TA CH CYA 1.6 7.6 N/A 100 ~220 ~45-50 11 (shock) 7.6 N/A (shock) 100 3.0 (pool guy didn't come for a few days) 7.6 0 100 250/260 60 10.4 (pool guy came again) 7.6 ~0 100 260
So, with this info in hand, and with the PoolMath tool, I'm still not 100% sure what I should do next. The different goals on the tool have me wondering what I should tackle first, or if I'm good as is.
The big fluctuations in FC are the result of two things. (1) some algae (I think) growing in the shallow beach access (gets the most direct sun) and on the top step. The water never clouded and nothing grew any where else deeper than about 10 inches. (2) The salt cell may be going bad, so it is shut off and the pool is being treated as a regular chlorine pool with trichlor (I think) tablets in the skimmer. I am not 100% sure when the pool guy added the trichlor, or exactly when they added additional chlorine for the shock, but I assume it's correlated with the large FC increases.
I have not added any chemicals, but I am hoping to get to the point where I can manage this pool on my own with regular testing and a good understanding of how to triage issues.
Any guidance? Thanks.
