So I am ashamed to admit that I have not been tracking my pool chem levels every day like I should. I have been adding at least a gallon of 8.25% bleach in the evening and was shocked to see the onset of green algae. Luckily I caught it VERY early so I should be able to deal with it. But this is the first time I have dealt with algae. So I went to task and measured FC and CC using the FAS-DPD test (after adding bleach to start the SLAM process) and FC = 15 and CC = 5. What I am really surprised at is my CYA level is ZERO!! I check this fairly regularly and always had a CYA level of at least 30. I am not sure how CYA got to 0 but I have to assume chlorine was being consumed too quickly, esp in this Houston heat (and we've gotten some rain recently).
Is the presence of algae and/or the high FC and CC levels skewing the CYA test results? I have CYA on hand and can add some now.
The FC level is a little above the shock level of 10 per The Pool Calculator but not much I can do about it now.
Now that I have raised FC to shock levels how often do I need to perform the FAS-DPD test to determine how much bleach to add? Also, at what point do I know I can stop keeping FC at shock level?
I have lots of 8.25% bleach on hand and I am keeping the pump on 24/7.
