Thanks for the reply. I stopped mixing msp and now juzt using nature 2 silver ion and chlorine only. The MSP was irritating my skin I finally figured out. I think I will stick to 6 to 8 weeks for water change the way I use it.... I have a well and water doesn't cost me anything to fill the tub....

I have had my tub for about 6 months. I use it twice a day. What should I expect as far as water needing to be turned period I am finding about six weeks the way I use it it is ready to be changed out. It is a 280 gallon three man tub. It is a silver ion filtration system and I use chlorine and a little MSP combined for sanitizer. I refresh the filter and change every two weeks. I guess I'm just looking for thoughts and anyone who has experience with the tub that gets use this much if that is normal.
