Has anyone seen this before!?! My hot tub is less than a year old it's a Dynasty Palm Island II everything works great it has lots of extras like the ozone thing a gecko motor blah blah blah... But after only about 2 months in these little flakes started to appear, I have been a stickler for checking the water chemistry at least 2 times weekly. At first I really thought it was like someone's dead skin that came off 🤢 but it gradually got worse even after shocking, lowering the PH, water changing. We stored it for the winter after about 3 water changes for cleaning and pulled it back out, they are still here!! Bigger and way more, 4 water changes, shocking, vinegar, bleach testing for biofilm (didn't desolve by the way) it's still here, less but they are so big. I haven't found anything on the same level. My dealer is dumbfounded, I'm stuck.

Hi ive had my hot tub for 8 months now and i have completely brought this issue upon myself. I havent used the hot tub for the last 2 months but left it running. So a week ago i decided it was time to get back in it. I noticed small yellow flakes at the bottom of the tub, nothing floating, no sort of mold or foam just the deposits on the bottom. Ive contacted a few places to see if they had any idea what it was and i was told biofilm. I am now £120 into cleaning products and 4 days in to scrubbing the hot tub everynight after work. The last product i used was ahh-some it foamed up right away and the foam started to slightly yellow around the edges. I followed the guidance and wiped and wiped constantly then fully drained down cleaned every single area i can get to and ive even used a brush rod to clean the lines from the pump. Ive just filled up again and ran the jets and im still seeing the same small deposits in the water. Im at my whits end please could someone advise on what i am doing wrong or if it is infact biofilm, thankyou.

I picked up a 2002 Hot Springs Prodigy as a flip tub. It had been frozen, and has multiple leaks as a result. Hot Springs are the WORST tubs to do plumbing repairs on, due to the piece-built tongue and groove sides and extremely hard foam that channels water, making it a true joy to locate the leaks. But I digress... I am (obviously) cutting out some damaged pvc, and I noticed that there is a biofilm buildup inside the pipes. This is nothing new to me, having been repairing spas for 25 years, but I thought some of my new friends here on PoolSpaForum might not have ever seen it. Except @CanadianSpaTech, who has undoubtedly seen more than he wants to of it. 😉 I even hear that some doubt it's existence, and think that Ahhsome puts stuff in to cause the gunk that comes out. 🙄 So here it is: Here you can see where I wiped some off. That is a different pipe than the first pic, btw, so you see it is in every pipe in the tub. That's alot of square footage of surface area. And alot of nasty gunk. A little history... I have never been a fan of purge products. I have tried a few over the years and had poor results, so I stopped using or recommending them. Once I started on PSF and another forum I frequent (about a year ago), I started hearing about Ahhsome. I read threads, watched videos, chatted with @dllenoand @Ahhsomeguy, and was convinced. But I had never used it myself... So I reached out to Ahhsomeguy and made him a little challenge. I proposed to run his product in this tub (after I complete repairs) then cut open a pipe and look. Forget scientific test numbers, I am from Missouri, the Show-Me state. So show me. I had ahhsome delivered at my house 2 days later. He must have shipped it priority, or something. 👍 I will keep you posted on the repair status and test results with pics. I am kinda excited, but the tub has ALOT of leaks, so it may be a bit...

Hi, i am having problems identifying what the white flakes, some upto 5mm, are that have started to appear in my hottub water. I have tried adding bleach to a sample and the flakes are still there then i tried adding vinegar and the flakes are still there. I believe if they are biofilm they would disapear when adding bleach, but would they disolve and disapear if adding vinegar ? Thanks for any advice.

I’m looking for hope and guidance. We got a new spa, having never owned one before, and had trouble keeping the water clean from the start. Within two days of a fresh fill and one time sitting in it it started to get cloudy then smelled like a pond. Through out the next month we tried everything we learned about, but nothing helped for very long. Special shocks, different levels of sanitizer, mineral sticks, enzymes, clarifies, etc. So after three refills in a month we learned about biofilm, ahh-some and started purging the water. We have performed 8 full flushes, 3 including an overnight soak after the president of ahh-some recommended it. After recommendations from here and elsewhere we have done half doses hours after the initial full dose and then flush it. We have done regular agitation of running the jets 4 or 5 times throughout the day ......cleaning the disgusting yellow/green scum EVERYTIME thoroughly and skimming the foam afterwards because so much scum is within it. It does not feel like it’s getting better. After one of the runs it turned more green, so we thought we were on our way.....but no. The next refilled had lots of yellow too. It seems the half doses are more green then the initial runs. Am I doing something wrong? Will this end? I can’t imagine using this thing until it comes clean, but it seems like that isn’t happening. We have very very soft water here, so I’m not sure if that matters. I’m not balancing the water before hand because the president of ahh-some said I didn’t need to. I have been heating it to 90 or 95 after testing cold water, that seemed like it got less out. However the president said that was unnecessary. I’m using chlorine in every new fill, but maybe not enough? I’m not actually testing the level, should that matter? It takes SO much work to drain it completely and clean it completely to just have to keep doing it. And having a toddler to watch at home makes it very hard to do all this work, especially now that it’s dark so late in the morning and early at night. Any advice would be appreciated. This is such a nightmare. I have tons of photos, but I can’t imagine it’s helpful. Just evidence for when we address this with Sundance legally. PLEASE HELP! Thank you for any advice!

Bought my Sundance Chelsee new 9 months ago, and have fought biofilm on and off since the beginning. I now suspect the biofilm was present at initial installation (from wet test), and the problem has worsened over the past few months. Drain/purge products have not been effective in eradicating the biofilm. I have read countless posts on this forum, and used Ahhsome for the first time this weekend. Yellow biofilm evident in purge and re-fill. After second Ahhsome application, upon taking the front panel off the hot tub, vast amounts of biofilm were clearly evident inside tubing upon visual inspection (more than 50% of visible tubing covered in biofilm). I have let the second Ahhsome application sit overnight, and will tackle the drainage tomorrow. In this forum, I have read some are successful after 6 or 7 successive drain/re-fills, but am I wasting my time with purging methods for a case of severe biofilm? Should I call a tech and have the tubing manually cleaned?

Went outside today to treat my spa that I've had for 3 years and when I turned the jet air controls on I noticed lot of leafy greenish black material floating all over inside tub. There was a bad windstorm a few days ago so I figured a few leaves may have made there way under the lid as the back wasn't locked down. So I drained and cleaned the tub and as it fills up water is running out of the foot jets and side jets almost completely clean and clear. Once completely filled I fire up all of the jets including turning on the the air controls and more of the same material appears. See picture attached for a few of the flakes on my finger. When squeeze or press the flakes together it gets mushy and just disintegrates like a mud. Also, there are little semi-transparent flakes that look like dry skin floating around that appear to be creating a scum ring around my tub. In three years i have never had a problem like this. Some details on use/maintenance - Tub is used about once every ten days. It's been one week since I last treated the tub but can't recall how long since I turned on the air jets - maybe 2-3 weeks. Only thing I add to the water is Nature's Way Sani Chlor and MPS / Non Clorine Oxidizer. The Clear Ray UV bulb has been out for about 8 months. I drain and clean it every three months. Any help on what this might and how to get rid of it would be very much appreciated. - Thanks

We bought an AquaTerra hot tub at Costco about two years ago. We keep it meticulously clean and maintained. A couple of months ago we noticed a sticky film on every underwater surface, and when we got out our skin was VERY sticky. We drained and cleaned it repeatedly with no improvement. Finally, we called the manufacturer who recommended running a dozen or so bottles of Hydrogen Peroxide through the water for a couple of days, followed by Ahh-some. We are now on our fourth treatment of Ahh-some, draining and scrubbing between each, and nasty, sticky gunk is still pouring into the tub. This gunk does not wipe away with a rag. We are having to use a scrub brush, bleach and a lot of elbow grease. Even used the power washer - and the stickiness is still there! What else can we possibly do?!

Just flushed and drain this weekend. What a pain but worth it. I had my new spa for 1 month now and my god the stuff that came out...oh mygod upchuk! <back now> Put Ahhsome as directed with 10PPM bleach to shock. Run jets for 30 min. Get a terrycloth (easier but can scratch)/microfiber (preferred) towel you will be throwing away and wipe the ring of caked on crisco looking grease. It will be green-brown. Green is probably machine oil/grease from factory (it smells like equipment). Now here is the key point: DO NOT ATTEMPT TO JUST WIPE IT. It will be super sticky and caked on like grease in oven. Simply dip your rag in the spa and start wiping. Damp will easily remove this crap. Wring it out as you go. Ahhsome will bond the grease so it cannot be reintroduced into the water. If the gunk is thick, it will drop into the spa and lie on whatever surface it touches. Simply wipe it up with your nasty rag...the rag will encapsulate yuckies in cloth fibers! Shock it to 10PPM again (bleach) as your will have very little FC and run it again for 60min and repeat wipe off with another rag. Let spa sit an hour or two. Now shock water to 50PPM and run 1 hour. You will have very little gunk now to wipe off. Added 32oz H202, run jets 15min, and drain water. Once drained run all jets 10 seconds. Run blower/air 10seconds. Use shop VAC to remove all water from jets, then flush top jets with fresh water to move water out of lower jets. Suck this out too with shopVAC. dry the spa with microfiber. Add 1/8 teaspoon Ahhsome in 32oz spray bottle and clean entire spa. Any residual gunk will wipe easily with this solution. Refill SPA making sure to push water into top jets to make air bubble priming easier on startup.
