HELP explain free/total chlorine & when to oxidize?

Ok. Deep breath. STOP USING CHLORINE as your sanitizer! The only chlorine product you should use is shock. Bromine or MPS are all you need to sanitize, and only shock when you need to work past the ability of your sanitizer.

All of you need to find a local spa dealer who tests water. Bring a sample of your water and a picture of all the chemicals you have in. We should have a strong understanding of what these chemicals do and how they work together, to prevent damage to our tubs and us. Have water care explained to you with your water test results. Keep testing and asking questions until you understand. If you have had your spa for months and are unable to maintain water quality, then your missing a step or incorrectly using a product... you need to double check your method with a local professional who can answer your questions as they apply to your situation.

And clean your filters often! Like 2x a month, or once a week if your having water quality issues. This is the most important step in maintaining your tub.
