    SpaGuard Enhanced Shock - Chemical Breakdown

    I have been adding some SpaGuard Enhanced Shock lately and I found an MSDS for it that lists the chemical components as below... Can the group confirm that I am correct in the purpose of each component? 58.2% Sodium Dichloro-S-Triazinetrione - This is the stabilized chlorine component with...

    Bromine Level Not Rising from a Bromide Reserve

    I just refilled my 500 gallon tub and did a prep inclusive of an Aqua Clarity flush. After the refill I added 2.5 oz of Sodium Bromide that, per the label, was able to set a Bromide level of 30 ppm. I just came from a regimen that included Bromine tabs and weekly Dichlor shocks. After about...

    Dichlor Shock and CYA Buildup

    For the past year or so, I've done sanitation and shock in my 500 gallon tub with Bromine and MPS mixes. I've recently shifted from MPS to a dichlor-based shock. Since my shocks are typically no more frequent than weekly, should I have any concern of CYA buildup? I don't do any CYA testing...

    'Hibernate'/Shut Down Hot Tub for the Summer

    I have an outdoor hot tub and Summer is really heating up here in Texas. I'm thinking of shutting down the tub until around mid-September. Should I empty it and not run any motors/electronics for the 3 months? Should I leave it full, but only run the circulating pump from time to time and...

    SpaGuard Spa Complete - Thoughts?

    Anyone have experience with SpaGuard's Spa Complete product? Their marketing message is not really clear and there is no information on chemical composition. It sounds like a combination of a water clarifier, softener and scents. I'm thinking of buying it since I already use a separate...

    Quick Reference Card Share - K-2006C - Bromine Spa

    I spent some time making some modifications to the quick reference card for the Taylor K-2006C testing kit. There was a previous card that fit nicely into the lid, but it had a variety of things that were not of importance to me as a bromine tub user. I created a version that was adjusted to...

    PPM Bromine Decay Daily?

    I have a new 450 gallon hot tub and have been measuring how much Bromine levels drop when not being influenced through the additions of tabs or concentrate. It looks like my hot tub loses about 10 or more ppm per day without anyone swimming in the tub. My typical use is to keep the tub at...

    Any real difference between Taylor's R-0871 and R-0872?

    Taylor has both an R-0871 and R-0872 FAS-DPD Titrating agent that they sell separately under the guidance that you will need the R-0871 to measure chlorine and the R-0872 to measure bromine. The instructions seem very similar and in previous DPD test kits, you could use the same reagents and...

    How to Measure Sodium Bromide?

    How does one measure the amount of Sodium Bromide (Bromide Reserve) in a hot tub? I see all the usual drop and strip tests for Bromine, but nothing yet for reserve Sodium Bromide. What I do see is when my Bromine levels are testing low and then I oxidize with MPS, the bromine measure increases...
