I have a green pool, so I was going to start a slam. The results of my initial testing are as follows:
CYA = 70
FC = 19.5
CC = 0
I did not do a ph test since the FC was so high.
Leading up to this issue, about a month ago I had a little algae issue (I thought), so I started testing and found my CYA levels were way too high. I ended up replacing 67% of my water to bring my CYA levels down to 50. After the water replacement, I raised the FC to combat the algea. Within a couple of days, the pool was good again.
We have had an unusual amount of rain for West Texas and consequently the water got I little too cold. So I bought a solar cover about 3 weeks ago and put it on. Since then, I have not been as attentive as I should have been and then we went out of town for the holiday.
Now I have this green pool.
With an FC value at 19.5 and CC at 0 (been it these values since yesterday afternoon's test) how can it be this bad? With my CYA already back up to 70, I need a Shock level FC at 28. Is there something I am missing. Or do I just need to reset my brain and start the slam from here.
