Instructions: Keep the Chemi-pure Elite sealed liquid in the container until ready for use. Rinse the bag under running water for 5 to 10 seconds, then place the bags in a high-flow area of the sump, canister filter, or HOB filter.

Chemi-pure Elite should be replaced approximately every 2-4 months, depending on the bio-load. If using more than one Chemi-pure Elite filter bag, replace one at a time every week until all bags are replaced.
