Degrades fats, grease and proteins from food preparation wastes, as well as soap and detergent residues.

  • One application per tankfull. NO repeated treatments are required until your tank is emptied! 
  • Chemical FREE!
  • Safe for you - and safe for the environment!
  • Works with fresh water or salt water.

See 'Specifications' for dose rates


Dose rates:
Onboard tanks:
Add 50ml per 30L tank capacity through sink or shower drain. Add water to the tank to activate. Repeat only after dumping.

Large Grey Water Holding Tanks: 
Add 75ml for the first 200L, then 25ml per 50L.
Example: 1,000L tank - 75ml + (1,000-200) x 25l/50 = 475ml dose.

Great for recycling water from the laundry to use

I used this in my grey water tank at home. We run the washing machine rinse water into a wheelie bin and then run it out on the garden. With this product, there is no foul smell from the water and the inside of the bin is clean and odourless. Whereas before it had an awful stale water smell and loads of scum on the sides of the bin. Great product - and best of all, it is chemical free and safe for the garden.
