so you are saying I should just return the N2 and use ONLY dichlor and MPS? won't the spa smell like chlorine then? I thought the whole purpose of the N2 was to use LESS amounts of chlorine thus no real smell, etc.?
I am not saying use just dichlor and MPS. I am only saying this is what I have come to. Ozone and silver will help manage your water. The use of N2 will not reduce the amount of chlorine you add after soaking. IMO, the real benefit is when you do not use the spa, there is a low level bacteriacide working to help keep your water clean. When a spa is used, however, you need proper sanitation for healthy water. For this reason, I believe that daily soakers get less benefit from silver and ozone than do occasional soakers. Silver and chlorine are good companions.
D.P. Roberts is correct. Chlorine smell is not from too much chlorine but from used chlorine (chloramines) as well as burning eyes, etc. A properly chlorinated spa should never have a chlorine smell. The only way to eliminate chloramines is to reach breakpoint chlorination (shock with chlorine). Regular use of MPS keeps chloramines from forming. The two methods of shocking (breakpoint chlorination/MPS) are different processes. This is information that I am just learning. I always thought the two methods did essentially the same thing. They do not. Since I have been using MPS weekly, I find my free chlorine level lasts longer.
