How It Works

Chemi-Pure uses a combination of filtration technologies to help maintain aquarium water quality.

Activated Carbon adsorbs dissolved organic compounds and other substances responsible for yellowing, odors, and reduced water clarity.

Ion-Exchange Media helps remove selected dissolved impurities from the aquarium water.

Together, these filtration media provide convenient chemical filtration for maintaining clean and clear aquarium water.

How to Use

Place the Chemi-Pure media bag in an area with good water circulation.

Suitable locations include:

• Sump
• Filter chamber
• Canister filter
• Media basket
• Hang-on-back filter
• Other areas with strong water flow

For best results, rinse the media bag with clean aquarium water before placing it into the filtration system.

Do not allow the media to become completely clogged with debris. Replace the media according to aquarium conditions, water quality, and the manufacturer’s recommendations.

Important

Chemical filtration media should be used as part of a complete aquarium filtration system and does not replace biological filtration or regular water changes.
