Hi I'm back...I just drained and am going to refill my spa. Can someone send me a link to water bears bromine write up? Thanks...so I should be using the bromine tablets as they are blended with chlorine and not as strong..which I do.
You can shock your spa with liquid chlorine bleach instead of the MPS (potassium monopersulfate) shock you are using, works just as well. Chlorine does not exist in a bromine system with a bromide reserve in the water. It converts the bromide ions into your active bromine sanitizer, hypobromous acid. In fact, any oxidizer will do this be it chlorine, ozone, or MPS. The advantage of using bleach is that it forms chloride ions instead of sulfate ions like MPS. Chloride ions are a more benign constituent of TDS than sulfates and MPS is a known sensitizer that irritates many bather's skin.
Can you still do this if you don't have a bromine reserve? What happens if I have a bromine reserve and I forget to add bromine and the level drops and the reserve is used up? Do I add sodium bromide again?
So really all I need is the bromine tabs, borax, and baking soda..and check the levels..in addition to the dry acid. One last question on dry acid...can I just use leisure time spa down? will that lower both, ph and TA.
Sorry for all the long questions....but I'm trying to learn all this stuff.
THanks
