Welcome to our forum.
Thanks for the input. This really goes against all I have read and thought I comprehended. I know you can get an MPS reading by using the proper "clearing" reagent in the Taylor kit. Maybe technically it is called something else, but the instructions for low chlorine recipe of Nature 2 refer to maintaining MPS levels along with the experts who post here.
MPS will stay in the water until it is used up but it's primary function is to burn off combined chlorine and is in no way to be considered a sanitizer. The more dichlor you use the harder it will be to maintain clear water as it contains cyanuric acid which degrades the ability of the chlorine to oxidize which is how chlorine sanitizes water.Dichlor does not lower MPS levels. There is a lot of science behind this and much to lengthily to describe here. PM me if you want to learn more.
Hi all,I am still using the chemical procedure I listed earlier. The K-2042 interference reagent I ordered from Taylor arrived frozen so I still do not trust accuracy of the MPS levels I am trying to measure. While I am waiting for another shipment I wanted to ask others if they see a type of white residue on their step or elsewhere that water dried up from getting in and out?We have a black top to our step and I noticed when the water dries the white residue and am surprised in that it seems to point towards alot of chemical when I was striving for minimal.We still use our tub at least an hour each nightly at 99 degrees and I use about 2 Tbsp of MPS after to have maintained level 24 hours later at next soak. This does not see like too much according to Chem Geek and his estimates with 24/7 Ozone?Any comments are appreciated, especially if you have Taylor kit and MPS interference reagent usage.
