Neptune Systems PM3 Dissolved Oxygen Module

DISSOLVED OXYGEN MODULE :: PM3 REAL-TIME MONITORING OF DISSOLVED OXYGEN IS A GREAT SAFETY NET Many marine aquarists only give the oxygen content in their aquarium water a passing thought, not fully understanding how the level of the Dissolved Oxygen (DO) in their tanks can affect their entire tank population.  In one way or another, everything (fish, invertebrates, corals, algaes, bacteria) in the oceans and in marine aquariums react with oxygen. Most of the living beings of this planet require oxygen in order to metabolize nutrients. Fish, invertebrates, corals, and bacteria ingest O2 and expel CO2 day and night. MORE GET AN ALARM, APEX TAKES ACTION Should your aquarium O2 start to approach the danger zone, the Apex can alert you immediately by audible alarm as well as send you an email. But, that’s not all. You can have a couple of air pumps with air-stones on the ready in your sump and the Apex will turn them on if the O2 starts dropping too low.
