For those of you interested ...
It seems that 1 1/2 PPM it is not enough to keep the tub bacteria free. So I will be upping the dose to 3 PPM and that was my regular dose. The tub has been getting cloudy after a few days ... same as when I didn't use the Frog and used my regular dose.
But like Cola said in my 2 week info - the tub clears up really quickly without the use of a clarifier. I opened the tub yesterday and it was cloudy, put in 4 1/2 PPM chlorine and about 45 minutes later put in 2 oz of MPS to get rid of any CC. I opened up to a crystal clear tub today! I don't remember that with just chlorine.
I haven't been able to soak, but plan on it tonight so I guess I'll take notice if the water feels different.
