CO2 Systems & Equipment

Injected CO2 is the single biggest jump in growth and color a planted tank can make. Ambient CO2 in a closed aquarium runs far below what plants get in nature, so high-tech scapes supplement it directly.

Regulators, solenoids, diffusers, drop checkers, tubing, check valves and cylinders — everything from a nano paintball setup to a full dual-stage rig.

Target: roughly 30 ppm during the photoperiod, with the solenoid on a timer starting an hour before lights.
