Studied the site a bit in advance and did my homework a bit. Hopefully these details can help you, help me, fix my pool!
Details I know that will be asked for:
Size: 21' AG Pool
Filter: Hayward (Sand)
Tested with: Taylor K-2006
FC: 20 ppm
TA: 80 ppm
CH: 400 ppm
Saturation: appx. (-0.9)
So, my pool is a beautiful cloudy blue...not clear sadly. But, it did start off looking like a green swamp/fishing pond. So, I'm making some progress. I know pH is way low & CYA is way high. But, I have no idea where I really need to start. I've been scooping leaves, brushing, vacuuming (to waste), backwash/rinse, and skimming the top for about 3 days now. But, the cloudiness looks about the same since it turned blue, from green.
Products I have been using:
Clorox Shock Blue: 12 total tubes (12 lbs)(Stopped after day 2...when I learned about this site)
Clorox pH UP: 1.5 containers (6 lbs I believe it equates to)
Clorox Calcium Hardness Increaser: Appx. 1/4 of the container (seems to have got it balanced)
Clorox pH Protect: Appx. 1/4 of the container (TA is in range, but on low side I realize)
Clorox Chlorine Stabilizer: Appx. 1/4 of the container (I don't know if it's done anything)
Clorox Active 99 3" Tablets: 2 in floater
Clorox Water Clarifier 32 oz: 1 bottle (I don't know if it's done anything)
Hopefully this info can help someone, help me. If you need anymore info, please let me know.
