This morning I tested my water about 30 minutes after the sun came up, and FC was at 25.5. I just tested again and my FC is reading 24.5. (After being in the sun for about 4 hours) So I think it is safe to say that chlorine levels are holding. Also, I am not seeing any algea on the bottom of the pool. I am going to start letting my chorine level come down to around 9 or 10. (I measured my CYA level twice, and it seems to be between 80 and 90.)

Does everything sound ok? If I happen to see a little bit of algea this evening, could it be what I was unable to vacuum yesterday that just settled down, or would it mean that I definitely still have a problem? I don't think my CC is at 0, but it is definitely less than .5

Also, when would it be ok to test my ph again? How low do I need to let my FC level drop before I can get a good reading?

I think I am on the right path, but any help or assistance would be greatly appreciated.

Thanks

Tim
