We had a cloudy water problem over the weekend too...
I am also a new tub owner, so after searching this site, I did the following:
Clarifier
Shock
added Chlorine
Clarifier
Shock
Clarifier
Finally the water was clear after the 3rd dose of clarifier. Each time we did the clarifier, the tub foamed up pretty good with some icky stuff, so I scooped the foam out, and also directed some towards the filters.
This was over a period of 2 days, so we didn't do the clarifier 3 times in a row...which I'm pretty sure wouldn't be recommended.
Anyway, that is what worked for us. Now we are having a problem with off-the-chart bromine/chlorine readings so we haven't used the tub for 2 days now
but that's not your problem
I feel for you as a new tub owner and trying to get these chemicals down...I'm sure we're overdoing it, but live and learn!
Good Luck!
