OK, so for the first time in history I have a below 100 cya level. The bad news is that I now have a 0 level according to the test results. I could still barely see the dot with the test tube completely full. My filter has been running for 3.5 hrs since refilling. At that time I also added 3 gal. of bleach. I tested my water just now, 3.5 hrs post fill and bleach addition. I have attached my results here as you can see on the pool calculator.
I have questions based on these results.
1. With my TA so high why doesn't the calculator tell me to add acid? I thought the preferred method was to knock down pH (with acid) and then aerate? Instead it is telling me to add pH increaser.
2. If my cya is truly 0 do I have to go out and my stablizer or should I just used some stabilized trichlor etc for awhile? I am getting somewhat tired of buying stuff.
