Welcome to our forum.
I don't want to sound ignorant about this, but.... . I keep reading that folks are using MPS to help keep the spa clean. What is MPS? Is that a brand name or a shortened version of a chemical compound?
Well, I'm so glad you asked the question. I thought for sure MPS stood for "multi-purpose shock". Alrighty then.......here's my question.......we have an ozonator, use a nature 2 cartridge. The dealer has recmmended we add shock once a week.....that's it! All that's required for a spa maintenance. I would really like to have some sort of system that I can have confidence in....this one isn't it.
Is my multi-purpose shock considered MPS?
Stemay,I think you will find that most people on this website believe in dichlor as thier main disinfectant. 1 tsp for each bather after each use.
Wouldn't it depend on the size of your tub?
