A question I hope someone may help me with ...
First I have a 20x40 IV pool. Aqua-rite SWG and Hayward DE filter.
Last weekend we had a bunch of kids swimming in the pool and by Monday afternoon when everyone finally went home I noticed that it looked a little cloudy. I up the output on the SWG and covered it over with the solar cover. Monday it was really cloudy so I took off the cover and shocked the pool with bleach. My CYA was about 30 - still trying to raise it this year - and I shocked it up to about 20. It looked like I had a CC of .5. I added some more stabalizer as well. The pool cleared and it held the chlorine overnight. I still had a CC of .5 but I thought since the chlorine is still up there, it should keep working on that. By the way, when I shocked the pool with bleach I shut off the SWG. Since I was up to shock level and I wanted to acurately read if the FC was moving, I didn't want to keep adding CL. It's Sat. and I have not added any more CL and it's still at 9.5 with many a sunny day behind us. I thought I would have drifted down more than that by now. No CL added since Monday. Anyway, we did some swimming today - even though the CL is a little high - and the pool is cloudy again this evening. We did have some rain move through today, but nothing long term - just quick showers. I checked the CL and it's still up around 9. I don't want to add any more as I was hoping it would drift down to about 5 and then fire up the SWG and keep it at that leve. Why does it keep getting cloudy. Last week I backwashed the filter and the pressure is fine. Here are the rest of my numbers ...
CYA: 35 and rising
All the equipment seems to be working correctly. I would have thought that if I was fighting something it would eat the CL. Also, why can't I get the CC back to 0? Most of the week it stayed at shock level. BTW, this is the first year with the solar cover - a clear one - and at first I thought it was just getting the hang of using it but my CL never dropped below 3.
Thanks for any help you may be able to provide!
