I just tested for CYA and found I have zero. The black dot never disappeared. I failed the overnight test as well as I lost 2 ppm. This morning around 8 am I tested and it was at 10.5. I tested about 1215 and it was at 7. So a 3.5 PPM loss seems like a lot right now. So I am in the process of shocking and was wondering do I need to worry about CYA or not.
Each time I test for CC I get 0.
Here are the rest of my results which seems fine, with the exception of CH is a little low.
These results are from around 2 am this morning
CYA-0 as of 8 am this morning.
Edit: Water is crystal clear. I did have an issue with my pump leaking at a seal and got that fixed this AM so not sure if that would hinder any of the results.
