    Bromine levels last 1 day

    Most likely: this new spa needs a purge with a product like Ahhh-Some to remove biofilm in the pipes leftover from the manufacturing + testing + waiting for delivery process. But simply using it is enough to burn through quite a bit of active bromine. How high is the bromine level going after...

    Replacing the guts of a rotomolded spa

    So I raised up the tub, and looked underneath. Nothing accessible - just a few foamed in compartments and plain rotomolded underside. No luck there. Filled it up and once it was over 70F I gave it a healthy 8oz dose of Fix-a-leak and followed the label directions to circulate it with pressure...

    Replacing the guts of a rotomolded spa

    Yeah, that's sure worth a shot. Everything I can reach from the maintenance panel is bone dry like it should be, got a feeling if I get it tilted up on its side that there won't be anything else visible beyond the spray foam insulation but I can try.

    Replacing the guts of a rotomolded spa

    It finally cooled off enough outside to even consider working on and filling the spa. I bought a plastic weld kit (real nice product) and went at the crack that I thought was the source of my leak. I think I sealed it up nicely, but after filling the tub up I again had water leaking out...

    Bromine is always zero

    Weekly may not be often enough even with low use, especially if the tub hasn't been recently purged to clean out any residual biofilms in the plumbing, even if it's new. Any time the sanitizer hits zero there's an opportunity for microbial growth. I would add enough of the Renew to get up above...

    Bromine is always zero

    According to the MSDS, Leisuretime Renew is an MPS-based product. Did you at any point add sodium bromide to your tub as part of the startup process? Generally for a bromine system you establish a bromine bank by adding sodium bromide, and then 'activate' that bromide into bromine by adding MPS...

    Replacing the guts of a rotomolded spa

    Understood fully. This was a Wayfair buy with a COVID stimulus check. I'm certainly not re-insulating a fresh shell. I'll report back on how the plastic weld fix goes once my tools arrive. Thank you for the frank reality check.

    Replacing the guts of a rotomolded spa

    Thanks for those video links! I didn't run across them in my first few searches, these will be great. I've ordered a plastic weld kit (basically a soldering iron with a different head on it) and I have some scrap bits available from the stair-steps they sell to enter the spa. Still waiting on a...

    Replacing the guts of a rotomolded spa

    I've contacted several local spa techs who don't service this brand so I may be stuck here having to DIY, still have a message out with a couple more. And the manufacturer says any attempt to repair will void the remaining two years of my warranty on the shell. I'm not positive I'll be able to...

    Replacing the guts of a rotomolded spa

    Thanks @Mdragger88, definitely got a bunch of pics and made initial contact with the manufacturer. I'm hoping, if it doesn't void their warranty, I can try epoxy and check back in with them in a month or so to complete the replacement or not, depending on how things go. Unfortunately the...

    Replacing the guts of a rotomolded spa

    Hi there. I have a rotomolded spa that has developed a small crack inside below the water line that seems to have given me a slow leak underneath. It is within the manufacturer's warranty period and I'm hoping they will approve a replacement, but they say a replacement will consist only of a...

    Soft or Hard water for a spa fill?

    250ppm is a near-perfect amount of calcium hardness to have in a spa. I would stick with unsoftened water unless it is very inconvenient to bypass the softener. Are you sure about the "utilizes no salt at all" part? From the page you linked - "It simply regenerates with 2 boxes of common table...

    Soft or Hard water for a spa fill?

    Depends how hard your water is. All the hardness that resin pulls out gets replaced by sodium + chloride ions (or potassium + chloride ions if you use KCl softener salt). If I fill with softened water, I have to add calcium to get the CH up where I want it, so I'm just adding back what was...

    switched spa to bromine.

    You may have simply not added enough sodium bromide. I use a product that is 99% sodium bromide and add 26 grams to my ~180gallon tub on a new fill. I'm not sure the volume of that 26g but I think it is quite a bit more than 1.5 tablespoons. The product I use says to use a half oz (~14g) per...

    New Hot Tub with Bromine Sanitization - Initial Setup Questions and Tips

    11.25ppm of bromine seems fine to me, mine is frequently that high the next day after adding 1oz MPS after a soak. I'm not sure if there is a number that is "too high", only a matter of if you are raising the bromine so high that it has not yet come down to ~5ppm before you want to use the tub...

    New Hot Tub with Bromine Sanitization - Initial Setup Questions and Tips

    I have only been running our bromine hot tub for about 1.5 years at this point so I'm no expert, but I have some experience. Adding a slight excess of the sodium bromide should be no problem at all. Worst case, it just means your bromine levels will spike higher than they would have otherwise...

    Stiff air control on hot tub, replace or lubricate?

    Thank you very much! I assume these are all similar items and removal would work like I see in YouTube videos for other spa air controls. It seems like parts/dis/assembly information is pretty minimal out there. I will give it a shot and see what I can do.

    Stiff air control on hot tub, replace or lubricate?

    Hi there, I have a 2021 AquaRest spa that has been in operation for about 7 months. This spa has two air controls to control bubbling on each side of the hot tub. On one of the two, the control knob has become very stiff to turn in the last month or so. The other one turns freely so I don't...

    Cheers from Vermont

    Hello from northwestern Vermont from a new 180 gallon 2 person hot tub owner with frequent use. Working through some issues on my own with the excellent resources here, but signed up expecting to eventually need to seek some help. Cheers all and thank you for this site!
