Hi all; been a long time since I've posted here, and several years since my original experiementation with ahh-some and biofilms that started way back in 2013. As most know, the makers of Ahh-some have produced another interesting product by the name of Aqua Clarity, which I'm sure needs no...

Greetings all, I haven't been quite as active in my spa experiments lately, but I just finished up a couple of interesting ones. the write-ups are posted on my hobby site rvdoug dot com, but I don't want to just post a link here because it might look like spam. so PM me if you are interested...

Greetings all, in case you are interested in my work over the last few years, I have just completed another purge shootout, comparing two "new" (to me) products to ahh-some. The first, is produced by SpaGuard, ("System Flush") which really isn't intended to release biofilms but i tested it...

Greeetings all, I haven't posted here for a while but some of you may be familiar with my work in testing various purge products, and this has grown to a data-driven understanding of how these products work. Those who have seen my posts know that I have done head-to-head comparisons with...

I'd like to start a discussion about sanitizer decay rates. I'm getting 1.5pp. Per 24 hours. What are your numbers? Note that my spa has an ozone generator so my decay rate should be worse than normal . My observation is that measuring decay rate as a percentage isn't very useful because...

Greetings and biofilm solutions to everyone . I have just completed a head to head shootout between ahh- some and a "new to me" purge product called "oh yuk". You may recall that I performed a series of experiments a few years back and found that ahh-some handily beat out a few other...

Hi all, I'd like to make reference to an interesting article about drain intervals. I've posted this information in another forum as well, but I wasn't sure if it was acceptable to cross post so I'll repeat my text below: Those who have followed my posts know where I stand on the subject of...
