Thank you for replying to my question. I'm wondering if I empty my hot tub (which holds 200 gallons) how much mms (activated or unactivated) I should put in just to keep the water clean and fresh instead of using bromine. Right now I'm using 3 caps of bromine granules after each session of hot tub. I use a ph level strip to test the levels and then when necessary, I use ph balance. I'd like to switch to mms or cds only for keeping the water clean and fresh(not for therapeutical purposes as I bathe in mms in my ordinary bathtub. )
