    • Very Expensive, but Helps Keep the Hot Tub Hygienic
Review Image by An American consumer An American consumer
Hot tub operation and care can be tricky. There are a lot of gimmicks and useless products out there, but this is not one of them. I purchased this product after noticing the beginnings of a white fungal buildup in my tub. After using this product's companion, Total Cleanse, before a drain and refill, I began using Hot Tub Serum in my tub on a weekly basis. I have noticed a definite improvement in water quality and clarity since introduction of this chemical into my care and maintenance routine. I use a bromine-based sanitizer system and Hot Tub Serum plays nicely with it. The only drawback to this product is that it is hideously expensive. Essentially it costs about $6 per dose—making it by far the most expensive hammer in my chemical toolkit. I have researched this chemical and it appears to be safe by all accounts (this statement should not be construed as constituting medical or safety advice or endorsement, as it is my personal opinion only), and it is effective, so...it's up to the consumer to determine whether it's worth it. In my case, being able to eliminate a white fungal infestation, I'd say I did get what I paid for. One other note: I was pleased with the way the seller packaged and shipped the product. It arrived intact and undamaged. I had purchased this stuff earlier from another vendor, and was dismayed to find that the bottle had been damaged, and about half of the contents had leaked.The soggy, sweet-smelling cardboard carton sitting on my porch alerted me there was a problem; I'm not sure why the shipping company hadn't noticed. To be clear, the bottle I received from Unique Solutions, Inc., was intact and undamaged, which was a relief, given the high cost of the product. It would be great if eventually they offered a powdered version of this material that could be home-mixed to the proper strength by home chemists like me, but I realize we live in a world populated by dummies and anarchistic ne'er-do-wells, so the U.S. government probably won't be giving clearance for such a thing in my lifetime, and this stuff will remain hideously expensive as a liquid-only solution. Bottom line: this is one of those spa chemicals that truly delivers what it says it is supposed to deliver. It is easy to use (but you really should invest in a graduated cylinder if you don't already have one so you don't waste any of this "purple gold"). I plan to continue using it as a normal part of my care and maintenance routine as long as I continue to own a hot tub. I don't give many things five stars, but this is one product that deserves it. ... show more

    • THIS PRODUCT IS FANTASTIC!
My tub was giving me Pseudomonas folliculitis and no matter what I used (Swirl Away, AquaFinesse), it would return within 2 months. I read the reviews for this product and decided this was what I needed to purchase. When the bottle arrived I read the instructions but it didn't sound like what I had been reading about in the reviews. I found the company's phone number on-line, called them, and discovered I had ordered the maintenance product and not the cleaning product I needed to clean out the pipes. They sent me the small bottle of serum along with explicit instructions on how to use it to get rid of the bacteria once and for all. I was amazed that it works exactly like so many people described in their reviews. My hot tub vendor did not give me good instructions on chemical dosing - just said to "shock" it every so often and bring water in for them to check. This company gave me simple daily and weekly instructions and the water chemistry has been perfect for several months. The weekly maintenance product keeps the water smelling good and so clear it looks like new. Yes, it's expensive but worth EVERY penny not having to change the water every two months! ... show more

    • The hot tub repair company recommended this to me!
Review Image by Regina Regina
I'm so grateful the hot tub repair company recommended this to me! Not only does it keep the water clear and smelling fresh, but it has also over the last several months, helped remove the old calcium build up. On my second bottle of this and the spa is better than ever!

    • Expensive
There is no objective means of telling if this works. They say my pumps and heaters will last longer. I use a dosage as prescribed for long term maintenance.

    • Hot tub water sparkles
My hot tub water has never been better. It sparkles. The tub feels so clean. $130 is kind of a steep price, but it keeps the tub so clean.

    • Amazing product
For years we alternated between bromine and chlorine and a host of chemicals to keep the water clear. No matter what combination we tried, the water would look great for a few weeks after filling and then it would get cloudy/scum line, etc. and we just ended up ordering more and more chemicals to no avail. I saw this product on Amazon and gave the company a call. They spent 20 minutes on the phone with me and walked me through what the maintenance would look like. 5 months later, and we're just about to run out of the first bottle of serum and the tub still looks and feels like the day it was refilled. 450 gallon tub, so we add about 4.5 oz. every week (never skipping). Instead of a rotation of at least 10 different chemicals, all we use now is the weekly serum treatment, chlorinating granules, Leisure Time Renew, and a foam down product. A handful of times I needed to add Spa Up to get the levels right, but it's been really simple to maintain aside from spraying down the filters once a month or so. If you're frustrated with maintaining your hot tub, as I was for years to the point I wanted to get rid of it, get this product and enjoy your tub again! Wish it was available 7 years ago. ... show more

I’ve been struggling with my hot tub to stay clear despite regular cleaning, balanced chemicals and draining every 3 months. Using this product every week has been a game changer. My hot tub looks gorgeous. This is worth the crazy high price!
