Does your aquarium suffer from low pH? Using carbon dioxide adsorption media helps raise pH on aquariums that are in closed buildings that lack fresh air.
Add this media into a reactor and attach it to your protein skimmers air intake. CO2 depleted air is drawn through the reactor into the protein skimmer which then draws the CO2 from the tank.
1 Lb - Treats 40-75 gallons. Media is exhausted when it changes from white to pink.
