I looked and saw maybe 100 threads on cloudy water but almost 99% of them didnt seem to match what I have so I wanted to ask just to make sure.
Pool info is in sig line. Pool was crystal clear and 84 degrees prior to a 10 day vacation. Got home and there had been record heat and almost no rain. Pool water level had dropped to where the skimmers weren't working well (still had water in them though) and water had risen to 94 degrees. There was algae in the pool in my "normal" spots. I say normal because I have two areas that dont get much water circulation, one in a far corner and one just under my Poolskim device. If we're swimming every few days or I run our cleaner than it never surfaces. If I let it sit over a week or two it will just start showing up. This time there was a decent amount of green algae in those two spots along with some accumulated pollen and dust/dirt on the pool bottom.
I tested the water and it was the same as normal day to day.
FC - 3.0
CC - 0
PH - 8.0
TA - 80
CYA - 70
My PH is always that high. I can add acid and it will be down a day or two and drift right back up. It never seems to get too high so most of the time I leave it and have read from a few threads and articles that some pools just have a higher PH.
So the first thing I did was run the robot, backwash the filter and brush the whole pool down. That really clouded up the water. I also set the SWG to Super chlorinate setting. This was all on Saturday. I've been testing the pool daily and the numbers havent budged other than the FC only went up to 3.5 after the Super Chlorinate run. I had two bottles of bleach left over from the Spring so dumped those in Sunday night. I also added in a half cup of DE to my sand filter as that really helped this Spring to make the water super clear from all the pollen we had.
Yesterday we went swimming - water still tested the same as the top numbers. The water just isnt "clear". It has this quality to it almost like doing a CYA test, it is a whitish cloud almost hazy looking. Normally I can see clearly from one end of the pool to the other wearing a mask (40') and right now I cant see the other wall at all, I can only see maybe 3/4 of the way across.
Last night I did the OCLT. I shut down the SWG but left the pump running as normal. I tested it at sundown last night.
FC - 3.5
CC - 0
Tested it at 8:00AM this morning
FC - 3.0
CC - 0
I am only testing to the 0.5 degree of accuracy using my FAS-DPD kit. Should I be doing the 0.2?
Water is still hazy. I have backwashed twice since being home on Sat and the water just looks milky from the DE that I add each time. Algae hasnt come back. Water is still hot at 94 degrees. Only thing new I tried today is I took out the regular filter screens on my Dolphin and added in the super fine pleated filters and am running it now. The other filters did pick up a lot of the pollen gunk but I was told these pleated filters are even better (Dolphin is new so this is my first time trying them).
Any ideas? I can SLAM it but my OCLT shows normal plus now that we are home my kids really want to be in the pool pretty much all day! I am a bit worried my FC is so low with the SWG cranked up higher than normal. I went from 40% to 80% and it really only gained 0.5. I may clean the cell to see if that helps since I have a lot of muriatic acid right now.
Is it the PH being at 8.0? I honestly dont know if it is much higher, the color test only reads to 8.0. Normally if I get worried I just add in the min amount of acid on the calc and that drops it so I have to think it isnt much higher if any than 8.0. Has anyone ever tried the digital PH testers? Thought that may get me closer but as I stated earlier I read a few articles that some pools just like higher PH's naturally and there isnt an issue.
