I think the Calcium may have been zero or very low ... I was using soft water and not adding any calcium. This forum is badass ... finally it seems I can find reliable and accurate answers. Thanks

I can't wait to hear the answer ... I have the iron problem as well and want to flush out my entire tub of iron stains ... then start over with soft water and add calcium ...

Sorry for the wrong info ... that is what a professional hot tub salesperson / chemical sales person told me. No wonder I want to blow up my hot tub with a stick of dynamite. Lots of misinformation out there it seems ... sorry to add to that confusion

OMG ... don't ever add chlorine to bromine

Right now I'm planning to flush the tub and start over to get a fresh set of readings upon filling. Perhaps I did it wrong but I don't think so ... I will let you know what I find out.

So, previously I had been testing for TH (Total Hardness) but after reading a lot here I am finding it not to be the same as Calcium Hardness. I buy the recommended Taylor Kit ... which has the chemicals to test for CH (Calcium Hardness). Upon doing so, it says to add one thing to get red (indicating calcium present) then another to turn it to blue (10X drops is the PPM). So, the first go at it and it turns a slight pink .. but after like 1 drop it goes clear, never to blue. What gives? I assume I have Zero Calcium or too little to detect? HELP
