Hi TFPers,
Happy Father's Day to all us dad's.
Uncovered the pool this afternoon only to see cloudy/murky water. Just last weekend, water was clear; could easily see the screws on the main drain cover. Now, I can see my main drain, but can't really make out the screws. Some background info: been covering the for about 1.5 mo. now, regularly add 12.5% chlorine (every 2-3 days about), test FC and pH every 2-3 days, VS pump is on 3 hr during day at 2400 RPM for solar/Polaris and 17 hr overnight at 800 RPM from 1800-0600, filters are new as of 4/15. Performed full testing:
pH 7.4
FC 6.0
CC 0
TA 60
CH 1150
CYA 30
temp = 91
Now, I don't understand what could be happening. When I got pool cover installed, I had a thread going about covers, and I remember reading a response that covers could cause some wackiness with testing/numbers. How could my water lose clarity all of a sudden (within a week or so)? How could it be murky/cloudy and the CC be 0?
The only thing I notice from my full testing today (I perform full testing 1x/mo. but test FC, CC, pH usually 2-3/wk) is that my CYA is lower than I expected. Last mo. it was 40. How could my pool be consuming CYA? For the last 1 or 2 mo., my chlorine goal has been 3-7 based on CYA 40. When I add chlorine, I usally add enough to bring up the FC to the upper limit of my range. FWIW, even with the pool cover, I'm losing about 1 ppm FC/day
I appreciate all the help. Tx.
Edit: I would have supplied pics, but can't find my phone.
