Happy Flush is a concentrated cleaner for cleaning internal pipe-work in Hot Tubs, Spas and Whirlpool Baths prior to drain down. Happy Flush is designed to remove calcium scale, biofilm, body fats and other unwanted harboured waste from the internal system.
Flush should be run through a system prior to draining your spa.
250ml bottle. Use a whole bottle per drain down (for spas up to 2000L)
Hi, what is the best water temperature to run this through
This product is arguably more effective at dislodging biofilm at a warmer temperature (above 30 degrees) but it can be run through cold and will still have an impact.
Can i use this in a lazy spa
Yes you sure can. Simply remove the filters, pop the jets on and run it through the system with the jets on. Then drain the water and refill fresh!
Hi, when I run the hot tub for the time specified on the instructions, is it better to have the pumps on high or low?
