I'm wanting to make sure our CYA is acceptable as long as our chlorine is at a working level/#.....I know our CYA number is high but we've partially drained and added water with hardly any variance in this number....draining the water in a 32K GAL pool is draining my wallet, not to mention the pool has been running nonstop. We went through a 30 day rough patch with cloudiness to algae and now we're clear again. I just want to keep it that way.....
We had to resort to the use of power powder in our final days of clearing our water. We live in a smallish town and finding plain, normal clorox was becoming a chore with local retailers sold out. Our calcium was low (25) which is why we chose the cal-hypo and are also guessing that use 3" tabs is what caused our high CYA and cloudy trouble to begin with. We're also going to start buying 8.25% bleach in bulk when we make it by our local Sam's
Current #'s are (from leslie's - our test kit has been ordered!):
FAC: 5+ (highest they can enter)
CYA: 100 (also think this is highest they can enter)
Someone recently mentioned keeping the pump off overnight for 12 hours and the CYA will raise to top and then we backwash (from top) and add water.
If our chlorine stays within a working level and the CYA is high is that ok and is it safe to swim?
This is our third season of pool ownership and our first issue....I'm wondering if it is because we didn't do a partial drain over the winter??
