CO2 Combo Regulator & pH Controller
The basics of any aquarium CO2 system are a CO2 regulator and a pH controller. These two components can be used to run a calcium reactor setup on a reef aquarium or to run a CO2 injection system on a freshwater planted tank. This basic Co2 Combo includes the core components and a couple extra parts for easy setup.
