Watermom,

Yes, I did a partial refill, about half. My original CYA test was over 110. Like I said earlier, after reading alot in here, after finding your forum, I realized that I needed to lower the CYA by draining and refilling.

I used quite alot of bleach after refilling with the idea of getting it to shock level of around 20 to 25. Water was a stale green cloudy combination. I kept adding bleach, but couldn't seem to get FC up high enough, which is when I posted. Testing with a Taylor 2006 kit.

But now the water is blue and not cloudy. Actually, it's looking pretty good. So I'm assuming I don't need to get to shock level now? I'm testing twice a day, and FC is around 3.5. Also, I'm seeing recurring small sudzy patches on top of the water. Is this normal? Just making sure of how I should proceed.

Anyway, love your forum, and appreciate any input. I'm a believer for sure.

Oh, and I'm in South Florida...we don't close for winter...
