Ahh-Some - Hot Tub Serum Cleaner Sachet | Clean Pipes & Jets Gunk Build Up | Clear & Soften Water for Hot Tub, Jetted Tub, Swim Spa | Top Clarifier Up to 450 Gallons of Water (One Time Use Only)

This product is as awesome as its name. My 3 year old spa had been setting unused for more than a year and I knew it was time test ahh-some. I followed the directions and added 2 tsp's to the tub and ran it for 30 min, wipes the gunk off the shell and did 30 more. Even more gunk came out the second time. I wiped down the shell and ran it yet another 30 mins. This time very little came out. So I drained the tub and wiped off the shell. Buy this product, you won't be disappointed. And for the people who claim it doesn't work, they might should watch some u tube vids to get an understanding of how to use the product. Follow the directions people, do that and you'll be pleased with the results.

It works better than the product description and I highly recommend it for anyone with a hot tub. Prepare yourself for the scarry gunk that comes out the first time you use it. Very easy to use liquid with a pleasant smell. THe single use packets are a great value. Make sure you rinser very well after you dump your tub.

Great product just dump and let the tub run a cycle. Cleans great.

I've had my hot tub for two years, with all of the ups and downs of ownership - mismanaging chemicals, not keeping up maintenance, etc. I've had a personal rivalry with biofilm, used too much chlorine and didn't even think about shock. While I've lived and learned, I've always maintained a 4 month drain-and-flush schedule, while using the store brand bought chemicals that take 24-48 hours to run through. This product is the real deal. I threw the contents of the packet in, and within minutes I had what I assumed to be the biofilm from the lines at the surface. After a quick skim, a rinse of the sides as the water was draining and the subsequent refill, it was done. The water was legitimately the cleanest it has been since I purchased the tub. No particles, no cloudiness, no oil film. I will use this every refill from this point forward. It's like a fresh start. Also: Don't sweat the cost - it WILL save you $$ in the long run.

This one use packet is very easy to use, my hot tub is about 400 to 450 gallons. You just squeeze the whole packet in and run it for about 30 minutes. It goes through all the tubes and pump and everything and eats all of the biofilm off of the sides. If you refill your hot tub and don't get rid of The biofilm in the tubes, your hot tub will get dirty very quickly. It feeds on itself and murckies up your hot tub. The chlorine or whatever you use doesn't really do the job to attack the biofilm because it won't eat through the layers stuck in the tubes. It's only meant to treat the molecules in the water. So that's what this product Is for, and as far as I know it's the industry standard for it. This is a great buy, I will be doing this at least every third time that I drain and refill the hot tub.
