    Gentle Spa - Amount per Hot Tub Volume = ppm

    How much Gentle Spa to get 30 ppm?

    How much Gentle Spa to get 50 ppm?

    I was told by Proteam 4 oz by weight per 150 Gal = about 40ppm.

    It is easier to measure fuild amount when adjusting for another fluid amount such as gallons.

    Proteam also said you cannot overdose Gentle Spa.

    My TA is 70 so I was thinking 30 ppm is corresponding amount of Gentle Spa.

    Is there another measure amount instead of oz by weight to acheive 30 or 50ppm?
