I wanted to support our new local pool supply store, so I went in to buy a new bottle of R-0600 for my Taylor Test kit. They did not have it, so they sold me a bottle of Poolmaster 1 Indicator Solution (for chlorine/bromine test). Looking at the bottle, it says it contains 0.14% OTO and 5.14% HCL. The R-0600 bottle says <1% OTO and <10% HCL. But it doesn't get any more specific than that.
Do you think the Poolmaster solution will work?
