Re-MOVER PLUS 16 oz. (100 gallons) - Dr. Tim's Aquatics
A high capacity, porous media that provides superior bio-filter surface area for the growth of bacteria which remove ammonia, nitrite, nitrate and organics.
Use 1 cup (240 ml) of Re-Mover PLUS™ for every 50 gallons (190 liters) of water. Re-Mover Plus™ does not usually have to be used in a filter bag. Place in your sump, filter, canister filter or other part of the system where there is good water flow. Re-Mover PLUS™ does not need to be replaced, it can be rinsed and re-used if necessary.
