Total Cleanse Gel, Hot Tub Cleaner, Purge & Flush, Works with Both Indoor & Outdoor Hot Tub & Spas, Clean Pipes & Jets Gunk Build Up, Purges 400 Gallon Water Tub 4 Times (2 oz)

Wouldn't clean my hottub without it! Removes all the biofilm and gunk! I have purchased multiple times!

This stuff works great to clean out the plumbing in the hot tub. I couldn't believe all the crud and oily scum that it removed from the plumbing. Just a small amount is all that is needed and let the tub run on high jets to give a good cleaning.

The media could not be loaded.  This stuff is great for cleaning out the plumbing in your hot tub before draining & refilling. The stuff that comes out is disgusting! I’ll never drain my tub without using this product.

Instruction say use 1 levelTeaspoon Per 100-125 gallon hot tub.So with my 524 gallon hot tub I used about 4.2 teaspoons ( all leveled). Very little left maybe about 3 teaspoons?Working it now, if definitely foamed and browning colored foam is coming out.I’ve used the set 2 before and it works.My only complain is the size of the container, but I’ll probably continue to use it.

To provide some context, I purchased a house with a 2014 Marquis Spirit. I never owned a hot tub before so I was unsure as how to properly clean it. After some research, I drained the tub and scrubbed everything and replaced the filter. When I used the tub for the first time it was at night. I noticed several white flakes in the water after running the jets. To make a long story short, the previous owners neglected the hot tub for about 18 months. I called out a hot tub repair service and they informed me that I had a biofiilm problem. I paid $300 to have the tub purged. I thought this would solve the problem, but I noticed a scum line the day after they purged. The tub would also fill with white flakes after running the jets. I called the company and they said this was normal and should stop after a few cycles... It didn't.After some more research, I read that Ahh-Some was the best product on the market. I ordered the large container and purged the tub 3 more times. Not only did I purged the tub, I vacuumed out all of the jets after purging. Much to my dismay the white flakes didn't go away. At this point, I was debating cutting the tub in half with a chain saw out of frustration.In a last ditch effort, I bought some Serum Watercare Total Cleanse Gel. I purged twice before draining with this product. After I purged it the second time, I let the product sit in the tub for a week (I live in Oregon and it was pouring rain for a week straight). Then I drained the tub, vacuumed the lines, and scrubbed every surface of the tub with "Off the Wall". This was the fourth time that the tub was purged.I refilled the tub and also purchased the "Hot Tub Serum Total Weekly Maintenance" product which is what this company recommends as the second step to the "Total Cleanse Gel". I have not seen one white flake sense. I am going on 3 months of using the tub since refilling and the water is pristine. I took it into a spa shop to have my water tested and it came back great. The only thing even remotely wrong with my water was I am approaching the Total Dissolved Solids (TDS) limit. Of course, this is due to adding the other chemicals and shocking and not as a result of using the Watercare RX products. As you can imagine, I am extremely happy with both products purchased from this company. If you have a biofilm problem don't waste your time with other products, use the Total Cleanse Gel and Weekly Maintenance Serum. I add the weekly product every Sunday and will be re-ordering once I run out. These products turned my hot tub from a nightmare into something that my wife and I enjoy a few times per week.

Good experience

Not sure how effective this is. You put in a dab and it takes a good while to dissolve. It leaves scum that you are not sure if it came from the hot tub or the gunk you put in. The container is very small.

One word you don't often hear on the spa showroom is biofilm. But it's there and will need to be cleaned out every time you change the water approx every 3 months. I keep my spa "meticulously" clean but use this serum to clean the internal pipes before draining the water. It's amazing what it flushes out. Greasy, brown biofilm coating the internal plumbing where it can't be seen. Even if your water is sparkling clear, trust me, you have it and need this (or a similar) product to clean out the pipes before adding fresh water. All I know is this stuff works (see photo). I also use their other liquid serum for weekly maintenance. That also works, but you still need this product for quarterly flush.

Not really sure if it does anything but it makes the tub foam. Been told this is a good thing as it kills the bacteria.

I’ve used many different products to flush the lines in my hot tub. This product was by far the most effective and took the least amount of time. Cleanup of biofilm was also easier than other products, leaving the biofilm less sticky. Highly recommended.

It works great but not like YouTube video
