I Have been a spa owner for 3 weeks now and about to do the 1st system flush prior to the first fill on my spa, a 2 yr old sundance maxxus. I have spend countless hours trying to understand a very basic setup to maintain my own spa and the more i read the more i realize theres more ways to mess up then there is to maintain it, and that of course all depends who you talk to next. The local sundance dealer guy told me after the flush cleaning, refill and add 3 cap fulls of ph down, 1/2 a cup of baking soda and two tablets of bromine in the tablet holder near the filter and i should be good to go, 580 gals worth of good times right? Then i read posts that say you should test and add this and that while in the middle of a party or BBQ or 45 min because so many people are using the spa. Did i miss something here? It is normal on a sunday BBQ that kids and adults can spend a whole day climbing in and out of a spa at a party and you mean to tell me this water and chemicals can not withstand a full day of use without having to be testing and adding chemicals to it during the party without someone getting sick or itchy, or am i just taking it to serious. Thank you for letting me vent! I am planning to use molson example 'HOW TO USE BROMINE IN MY SPA" to start off with because it looks as he knows whats going on in his explanation. The example i have seen for testing after system flushing Decontamination steps deals with putting chlorine and see if the 10 ppm drops, if it does not your ok, but what happens after your done cleaning and all that chlorine is still there, since i want to use bromine not chlorine what issues might i have or will I or do i have to dump it and do a third refill. Well thanks ahead for any input.
