AQUARIUM SYSTEMS - Waste-Away Gel Marine Medium - Gel Bacteria (x2)

Organic waste destroyer, 100% natural aquarium cleaner.

Waste-Away Gels continuously release good bacteria into aquarium water. These good bacteria consume nitrates, phosphates and organic waste while keeping the aquarium cleaner and the water clearer.

No need for metering pumps, tubing or connections. Simply unzip the clear wrapper, remove the tab, attach the included suction cup and stick the gel anywhere in your aquarium.

The gels last up to 30 days and will change colors to indicate they need to be replaced.
