Two little fishies Carbon Dioxide Adsorption Media - CDX 750ML

Introduce carbon dioxide adsorption into your system if your tank continuously suffers from low pH. This can be caused when aquariums are in closed air buildings.

• Add CDX media into your PhosBan Reactor
• Connect PhosBan Reactor to your protein skimmer's air intake with a CDX Adapter
• CO2 depleted air is blown into the protein skimmer which then draws the CO2 from the tank
• Available in two sizes - 750 mL jar will last about 6-8 weeks in the average 50 - 100 gallon reef aquarium. CDX Media is exhausted when it changes from white to pink.
