My pump and pool vac broke so I've been getting them fixed the past couple weeks. In the meantime, my pool turned from blue with brown algae (assume this was mustard) on the sunny wall to a cloudy green swamp. Everything was fixed as of yesterday so I started working on the chemicals last night.
I don't have a good test kit, just strips.
Start (last night):
FC - 1-2
CC - unk
pH - 8.2 (if I remember right?)
TA - 100-120
CH - unk
CYA - a TON! - 150+
Borates - unk
I added 3/4 gal of acid, then 1092 oz of 6% bleach. About an hour later, the test strip showed FC super dark purple and CYA looked like it came down 90-100. I added 4 gallons of 10% liquid chlorine.
In the morning it was still cloudy and very green (though a little less so). I brushed, backwashed a couple inches, and refilled the pool.
On my test strip, FC was still super dark purple. I took a sample to the pool store and they tested:
FC 3.0 :!:
PH 7.6
TA 100
CYA 100+ (their test didn't go any higher)
I thought maybe my test strips were old and bad and they gave me a new sample bottle. When I got home, I tested with the new strip and FC still showed super dark purple! :?
In any case, I added 6 gallons of 12% liquid chlorine and 1 quart of acid. Tested 1.5 hours later and FC was still super dark purple. I added 4 more gallons of chlorine and left for the day.
7 hours later, my pool is cloudy gray, very slight green tint, with brown algae on the steps/sides. I brushed, backwashed a couple inches, and am now refilling. Algae is not brushing off very easily, but better than it was.
Latest test strip:
FC: super dark purple
PH: 8.4
TA: 100
CYA: 300?? The test strip shows a color this high and was pretty purple, but this seems crazy!
I have 6 gallons of chlorine left right now. I can get more in the morning. I've added 3 quarts of acid already. Should I add more chlorine tonight? :?
