Puretec Tanksafe is a liquid treatment for rainwater and stored-water tanks, and the 15L bottle is sized for large tanks and rural / multi-tank properties. Stored water goes stagnant over time – algae, bacteria and odours build up, especially through summer – and Tanksafe keeps it fresh, clear and pleasant to use.
Added straight to the tank, it controls the microorganisms and slime that cause smells, discolouration and biofilm, so the water coming into your home or filtration system stays clean. It is a simple, low-effort way to protect a rainwater supply between filter services.
Dose according to your tank capacity and the label instructions. For households drawing drinking water from a tank, pair Tanksafe with a Puretec UV or whole-house filtration system for complete treatment.
