I just can't seem to get my pool 100% cleared this year Almost there, but still hazy. Here are my stats as of this morning:
CYA: ~25-30 (estimate after adding 4lbs to prior reading of 15)
Calcium Hardness: 30
I have a 20x40 vinyl pool that gets sun ~5 hours per day. Ran the FC loss test last night and there was no loss. There are no visible particles floating in the pool and I can see the main drain. It just looks like dull hazy water and it's been that way for 3-4 weeks.
I know the Calcium Hardness is very low, but does that matter in a vinyl pool?
Thanks for your thoughts.
