❓ Frequently Asked Questions

Is Co2Plus a replacement for a CO2 system?
Co2Plus is a supplement, not a complete replacement. For intensely planted aquariums with demanding plants, a CO2 system is more effective. Co2Plus is ideal for lightly to moderately planted aquariums.

Is Co2Plus safe for shrimp?
Yes — Co2Plus is safe for fish and aquarium inhabitants when used and dosed correctly.
