System Flush 24oz

Follow the instructions and this stuff cleans all kinds of foulness from your hot tub plumbing. I leave it running in the tub a little longer than recommended maybe for half an hour. Works well. Use every 60 to 90 days. Then drain and clean.

We have had a hot tub for 15 months. We use it everyday and keep the water in balance all the time and shock the system and clean the filter regularly. I drained it twice over the year (once by a spa service company and once by myself). The water has always looked and tested great. But as time went on, I noticed that the chlorine/bromine cartridges were depleting more quickly, from 4 weeks down to 3. We also noticed that the jets seemed less powerful. I investigated this and most of the blogs pointed to bioslime in the distribution piping. Apparently, the slime will create a disinfectant resistant layer on its surface which prevents the chlorine/bromine from reaching the organisms. As time goes on, it grown thicker, constricting water flow and consuming more chlorine/bromine. On the latest (the third) drain, I decided to use this System Flush first and then drain, clean and refill. WOW!!!!! What a difference, first of all after adding this, the water turned off color and was no longer clear. Now, after restart, the jets are more powerful and the chlorine/bronime cartridge depletion is back to 4 weeks. Even though the tests were perfect and my water looked crystal clear, there was growth in the pipes that I could not see. I will be using this regularly from now on. One lesson I learned was that a bit of dirty water remained in the pipes after I drained the hot tub. On start-up it was blasted back into the hot tub. All is OK, but next time after draining, I will flush the jet lines with a hose and then drain that dirty water out before refilling. The cost is reasonable and well worth it.

Worked well, I did not need to do the step more than once

Good price

1st time used today. It is quicker than past product flushing the system. Product seems to clean better than past product with less foam. It is more expensive though if it cleans better and takes less time it may be worth it.

Easy to use

This is one of the best I have used cleans the tub and the pipes

The product arrived ahead of schedule! It was easy to use and did the job it was supposed to do.
