Hello and thank you for the help in advance!
Here are some facts about my pool:
In ground
Vinyl liner
33,000 gallons
Auto cover
Sand filter
Variable speed pump
Heater & Chlorine auto feeder (both off now)
Basic care (normal): I shock using 10% chlorine liquid, use 3 inch pucks until CYA reaches 100, then for the rest of the season add liquid chlorine accordingly. I maintain my pool on a weekly basis, but we use it in season daily, so I'm always cleaning/checking it. Since we have an auto cover, I backwash every 2 weeks. I brush after I add chemicals, which is (as above) chlorine, an algaecide, and some SeaKlear clarifier (3 oz.)
This spring on opening, the water was very cloudy. After two weeks and with normal levels, I ended up bringing a water sample to my pool supply place. I had very high phosphates. They sold me a bottle of PhosFree and I have had crystal clear water for the rest of the season. I should note we've had a lot of rain in our area.
Thursday, September 24th, I opened my pool and found it to be completely cloudy. I was heading out of town for the weekend, so I backwashed, poured 2 gallons of 10% chlorine, algaecide and closed it until I returned on Monday.
Since Monday 9/28, I have been trying to "supershock" the pool to get some free chlorine in it. Nothing seems to be working for me. I'll give you some numbers:
9/28 Monday: 4 gallons 10% chlorine pm (that's all I had)
9/29 Tuesday: 6 gallons 10% chlorine in the am, 8 gallons 12.5% in pm
9/30 Wednesday: 6 gallons 12.5% pm (all I had) & backwashed
10/1 Thursday: 3 gallons 10% pm (all I had)
10/2 Friday (last night): 5 gallons 12.5% & backwashed
I have purchased all of the liquid chlorine I could find in my area, driving as far as 1 hour away (it is end of season, so finding some liquid chlorine has been a challenge). As of this morning, here are my numbers (using a Taylor test kit) :
FC 0.6 ppm
CC 0.8 ppm
pH 7.4
TA 190 ppm
CH 240 ppm
CYA 0
I am thinking I might have a bacteria in the pool, as my CYA has been super high for most of the season (running around 100), and now it is 0. I have turned off my chlorine feeder, as I am not sure I should add any stabilized chlorine to the pool. Please help. Again, I am having a tough time finding liquid chlorine because of Minnesota being at the end of the season. Most stores have shipped their remaining supplies back to the warehouses for the season, and my pool store has given me everything they have on hand. I am expecting more on Monday, but I don't know what I am doing wrong.
As far as the water, I can now "see" the bottom of the 8 ft., but it is still cloudy.
Thank you again for any advice you can give me.
