Hello, all. Just received and used my first K-2006 test kit. I'll try to keep this short and sweet. Had the pool (constructed sometime in the 90's, perhaps?) 5 years now, a few algae problems here and there, otherwise no real issues. Last few months pool has become very cloudy. Took sample to pool store, pool chemicals ok. Cloudiness not getting better. My new test kit shows these results, which are totally confounding me. Feel free to gently criticize, please!!
FC: 16.5 ppm (had to use 31 drops at 10 ml mark)
TC: no reading
TA: 40 ppm
CH: 260 ppm
CYA: too low on scale to read. I suppose I should say >100.
I'm posting to see what the HECK to do first. I understand that chlorine reading is off the charts. In the past I have shocked the pool to get this value down, but I don't want to do anything that's not purposeful. Thank you in advance. I'm hoping to get a handle on this! Suggestions, please.
