Spa Flush cleans the inside of your plumbing system - the pipes and hoses that are the heart of your spa - removing films and deposits without the use of harsh or toxic chemicals. Spa Flush contains no soap, detergents or harsh chemicals. Spa System Flush contains a unique, engineered molecule which actually breaks up biofilm in a way that no other product can do.
Scale build-up on your heater element can reduce heating efficiency and increase costs. Regular use of Spa System Flush also helps to dissolve these deposits from the pipes.
Making Spa System Flush part of your regular maintenance routine is easy and economical! When it's time to drain your water, simply add Spa System Flush to your old water and run your pumps on high speed for 20 minutes (or overnight at low speed). You'll be amazed at how quickly it removes oily films and other build-up. Then just drain it away, harmlessly with your old water.
No need to rinse before re-filling.  Compatible with all sanitizers.
1 bottle of Spa Flush will treat a 1500 litre spa twice.
