Hi all,
This is my first full summer with my pool. I had nailed the water balance and everything was going great. We had a ton of rain over the last 2 weeks, which led me to having to pump out some of the pool water to get it below the skimmer top a few times. I did keep checking FC and pH. FC would go up during rainy periods (SWG still running but no sun and no bathers) and I had to lower my SWG a bit a few times, but put it back to it's sweet spot once the weather cleared up. pH did not really move, even with all the rain (I run around 40ppm borates, so very stable pH now).
Anyway, with a lot of pool use in the last 4-5 days, I noticed that the pool was a little cloudy. I immediately checked and FC was down to 2ppm. I set my SWG to Super-Chlorinate (i.e. 100% for 24 hours) - in the past it would take no time to shoot the FC up. Not this time. I checked again 6-8 hours later and FC was still around 2. I dumped half a gallon of bleach to get it up there. Prior to putting the solar cover on the pool end of afternoon yesterday, FC was 5 (because of the bleach). When I checked this morning, it was down to 2 again. I dumped 1.5 gallons of bleach (which should add 10 FC according to pool math).
This morning's tests:
FC 2 (prior to adding bleach)
pH 7.4
TA 70
CH 300
CYA 50 (was 70 earlier this season, must've lost some during the pumping, although I can`t imagine I lost that much). I added some stabilizer this morning to hit my 75-80 CYA target.
BOR 40-ish
SALT 1600 (added 20 lbs this morning, should get me to 2000ppm)
TEMP 86
So, why is my water cloudy? Would the FC dropping to 2 cause this?
I've read that high levels of CH in high water temperatures can cause the CH to suspend in the water and cause cloudiness. Would that happen given my CH levels and temp?
My filter pressure is fine, not indicating it needs a cleaning. I do plan on cleaning it in the coming days once the stabilizer I added is fully dissolved.
I am having an issue with SWG though, which is probably why my FC dropped to 2. It seems like my flow sensor is not detecting flow when my pump is running at it's low speed (1100rpm), which is what it runs at all day. It worked fine up to yesterday. Perhaps my flow sensor is going bad or there is something restricting pressure in the line. It does detect flow when I increase pump speed to 1500rpm, which is what I've manually set it to for now.
Thoughts?
