Metal Gon is a concentrated formula that prevents the buildup of iron and other metals in spa water from refill to refill. Metal Gon sequesters iron copper and other minerals to prevent stains on spa surfaces. It is highly concentrated and only needs to be added to start-up. 

Directions

One bottle of Metal Gon will treat spas containing up to 500 gallons.

1. While filling your spa, pour the entire bottle of Metal Gon evenly into the water around the edge of the spa

2. Once the spa is full, run the filter for at least 30 minutes
