Fluval CO2 – Small tanks review
I personally use this in a 34L Fluval Flex tank and the carpet of hair grass has established its self in around 3 weeks from setting up the tank.
Use it along with your lighting to have the best effect.
If its a new tank with LEDs you’ll only need 1 canister fill per day along with 8-10 hours of lights.
This will create a great environment for your plants to thrive without creating algae problems.
