Instructions for Use

First Time Use: 

To ensure the water storage tank is cleaned and sanitized perform a “shock” cleaning treatment as follows:

Dose 20 capfuls of product into 1 filled 75 L (20 gallons) storage tank (3 capfuls of product into 10 L of water for smaller containers). Leave water treatment solution in the tank for a minimum of 4 hours, then rinse the residual sanitizer with water by emptying and re-filling the container completely.

Ongoing Usage:

Fill clean tank with treated/city/bottled water dosed with 1 capful of product for a 75 L (20 gallons) of water.

At the end of season repeat shock dose steps before winterizing the water tank.

For year-round use shock-dose once every 6 months for maintenance.
