I've been digging around this forum plus looked at Jason's calculator and am still confused about how much bleach to put in our pool daily, here's some background info...
We have a new IG gunite 12k gallon pool and have been using trichlor pucks in the inline feeder to maintain the FC levels (pool's been up and running for 2 months now). As you all know, this also adds CYA. I've been keeping tabs on the CYA level and have been saying I will switch to BBB as soon as the CYA starts to get up there. Well much to my surprise it's climbed a LOT faster than I expected. A month ago it was at around 25, 2 weeks ago it was 35 and yesterday it tested at 50 (all tests using the TF100 test kit). FC has been maintained at 2 ppm throughout. CC has remained at 0. Baking soda has been used to control TA (kept at 80) and PH has been remaining stable (7.4) since the first 2 weeks (before then I had to add acid to keep it down). The water has been nice and clear, no problems. But the climbing CYA has me worried and I want to switch to BBB before it gets too high.
So, my question is how much bleach do we need to put in daily? We will of course be doing daily TC and PH tests as usual and weekly full TF100 tests, but I don't know where to start. I tried Jason's calc and plugged in 2 ppm and it says 50 oz. of 6% bleach, surely I don't need to add that every day do I?
