one more cloudy issue

[dmr]

I have a 18' round above ground , vinyl liner, cartridge filter. Water was cloudy- almost milky, no algae, rain and hot temperatures(90's) Took sample in

cya 35,
chl 1.7,
ph 6.7,
tot alk 66

They suggested I add alk+ and ph- did accordingly to directions given- no change. I rinse filter once a day, add clarifier. Keeping filter going nonstop. Still cloudy. A few days later went back in

cya75
chl 1
ph 7.6
alk 215

They suggested 2 bags shock extreme and lower ph

Now it has been almost a week, some cloudiness still (can see about a foot and a half down), chl is showing about a 4, ph at 7.2 and alk is still high. I read about aerating, (doing that now), I am using liquid bleach now and have been adding a pint of muratic acid a day. Am I doing this right? We have had this pool almost 6 years and I have never had this problem.How long should it take to clear up?

I don't see how your CYA can go from 35 to 75 in a few days...especially if you added no CYA. I wouldn't trust whoever is testing your water any longer with numbers all over the board like that and get yourself a good test kit.

Regardless you should keep your pool at 3ppm FC minimum (more if 75 is the correct CYA number) at all times until it clears.

As for the acid don't let your ph go below 7.0 without aerating to get it back up. Unfortunately it's a LOT easier to raise TA than to reduce it.

Forgot to say that my strips had said I had no stabilizer in water, added too much. After their reading I stopped adding, As of today I can almost see bottom, still hazy but already my strip says almost no cya. Can you lose this in less than a week?

No, thats the strange thing. CYA levels don't go down except by backwash, splash-out and occasionally over a long winter.

Strips are notoriously inaccurate.
