    Spa Essentials - Spa Shock Xtra

    Saw that so why does it say on bottle "this product is not a sanitizer? In pool math how do I calculate effects of adding this product. I believe regular dichlor is 99%

    Spa Essentials - Spa Shock Xtra

    I bought it to do dichlor then bleach method. Was delivered today. Active ingredient, Sodium Dichloro-S-Triazinetrione 58.2%. Is this dichlor? Why does it say on bottle "this product is not a sanitizer?

    SWG indoor Spa - CYA Level

    After skimming through this post I got the feeling that for SWG's the CYA should be higher?

    Mikvah

    You are right and that's why a woman's mikvah is much easier to maintain. The issue is with a mikvah men use What would the CYA help in an indoor mikvah?

    Mikvah

    It’s definitely not equal to a spa. Was just the best example I was able to think of. Another thing that differentiates it from a spa is that due to the high bather load the water needs to be balanced/adjusted every day and if it’s being done manually and you wait at least half an hour between...

    Mikvah

    You can soak in it as long as you’d like to although typically people don’t spend more than 10 minutes inside. The filter can be ON. What you said would be true if there are only a few users but a Mikvah with high bather load there’s a demand for adding sanitizer while filter is OFF or you have...

    New to Bromine

    Please CMIIW but with chorine/bromine it’s not so accurate to figure out dosage by measuring how much sanitizer is in the water after introducing it into the water as you can’t know how how much was depleted by organic waste etc. Re CC. In a Mikvah/spa that’s being used by approx 30 people in...

    Thanks for your time dlleno. The reason I find it difficult -guesswork- is because due to my question below I think that MPS would be what I wanna use to oxidize and I haven't seen an exact formula to figure out how to dose MPS

    Thanks for clear response! How do you figure out dosage of MPS? I'm afraid of getting bromine too high as my spa -Mikvah- is used every day but on the other hand don't wanna go low...

    Thanks for reply. I have the feeling that chlorine is much simpler, you can figure out exactly how to dose by doing some calculations vs bromine + MPS where there's a lot of guesswork till you can figure it out. But what made us think of switching to bromine is that some claim that it's not as...

    Mikvah

    A Mikvah is used by Jewish people as a ritual bath. I’d say that it’s similar to a hot tub. It’s interesting to me that on a forum with so many members a search for “Mikvah” didn’t bring up more that 2 results. I have one and would like to hear the experts advice on the best way to maintain. A...
