Hi I was using test strips for the last few years with no issues in balancing as far as I know. Never any algae and the strips read in "ok" ranges.
Recently I noticed 2 or 3 green spots about the size of a silver dollars near the main and the water didn't seem as clear. Also the CC and FC were reading practically 0 on the test strips even though I feel I was burning thru the 3" tablets quicker than in the past.
Anyway I decided to get a k-2006 and first test my CYA was well over 100. The dot disappeared within a few drops. So I drained about a 3rd of the pool over night and refilled. I let the pump run for a few hrs before getting another sample and the CYA test is about the same. How much should I drain? Should I just drain it completely and start over? I intend to slam once I can get cya in the proper range.
Thanks,
Current levels after the partial refill.
