    Hot Tub Serum, anyone?

    congratulations! you have completed the rite of passage that many have not! Its just sad that mfgs don't get it. even worse -- that they (and the customers who believe them) are operating spas with this stuff hidden in the pipes, blissfully unaware. I talked to one mfg who specifically said...

    white particles in the hot tub

    if you are certain this is calcium scale (acid dissolving it, is strong evidence, I admit) then I think I would attack this a little differently. Since Scale responds to low pH you may need to do some more research on eliminating scale build-up without damaging your equipment. Lets have the...

    white particles in the hot tub

    Im scratching my head but just noticing the time coincidence. If the flakes appeared coincident with the ozone then that could be a clue that the residue isnt purely scale.

    white particles in the hot tub

    hmm. the introduction of ozone might be a coincidence or it might be important. it does sound like scale, but in any case I agree with RD and others -- I think you should do an ahh-some purge

    Hot Tub Serum, anyone?

    first of all -- the makers of ahh-some clearly know their stuff, and especially for the first drain/purge it is VERY important to remove the filters from their normally-installed locations. this is because ahh-some will/can remove large amounts of material which can clog up your filters and...

    Drained hot tub, ready to clean - now what?

    Im getting very positive results with "Hot tub Serum". And i have coached folks through multiple purges! Keep at it. Purge until you get an ahhsome dosed spa releasing no new material https://boisediesel.com/blog/2016/7/spa-purge

    Hot Tub Serum, anyone?

    Of course. Good stuff ! Man its good to see good science. Hot tub serum is epa registered for its intended purpose and due to its concentration cannot be considered a sanitizer. Disinfectant wipes and restaurant surface ckeaning solutions are orders of magnitude stronger concentrations in...

    Hot Tub Serum, anyone?

    Yea im well aware that adbacs have a clarifying property but its evident that, while there is no claim of sanitizing properties i don't think you can conclude that no bacteria was harmed lol during the experiment. Good to see that ADBACs have some airtime finally. Ahhsome itself ive shown...

    Tackle TA before adding chlorine?

    this! I find that chasing a TA number is just not fruitful. and in a portable acrylic spa you can afford to let the saturation index go negative; I find some surprisingly low TA numbers in my spa ( if you target the saturation index) , but they are a don't care. I'll test to make sure...

    Drained hot tub, ready to clean - now what?

    I usually save a bucket of ahh-some dosed water and use that for a cleaning solution . like the spray bottle idea though thats good.

    Hot Tub Serum, anyone?

    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...

    biofilms - why 1-3ppm FC is not enough

    Bingo. Lots of blissfully unaware folks have high sanitizer decay rates due to live biofilms and just cover up problem by adding chlorine

    biofilms - why 1-3ppm FC is not enough

    In your situation i would purge again. My spa was delivered with biofilms from day one. Took me several purges . This is my work that established ahhsome as the only serious purge product https://boisediesel.com/blog/2016/7/spa-purge

    biofilms - why 1-3ppm FC is not enough

    Yea you did the right thing. You can also save some ahhsome dosed water in a bucket for the filters. In fact i do that anyway for wiping stuff down. In one of my experiments i showed that biofilms accumulate in the filter media by cleaning them first with a degreaser. Then when I had a...

    biofilms - why 1-3ppm FC is not enough

    0 Got any references/ citations? This is precisely why a purge that breaks up and releases biofilms is most effective, and confirms why a traditional decon is relatively impotent in the fight against biofilms
