Bio-CO2 Pro (up to 132 gallons)

Grow Vibrant Plants with Easy-to-Use CO2

• Ideal for Planted Aquariums up to 132 Gallons
• No Refilling High-Pressure Cylinders
• Up to 30 Days of Reliable CO2 Production
• Refilling Takes Just Minutes

In freshwater planted aquariums, CO2 systems play a pivotal role in boosting plant growth, particularly for high light plant species that can be more challenging to maintain. The use of CO2 can also help plants outcompete nuisance algae, leading to a less frustrating and more beautiful aquarium. 

The Bio-CO2 Pro system combines the safety of biological carbon dioxide production with the convenience of pressurized delivery. Offering simplicity and unparalleled performance in an easy-to-use format, Bio-CO2 delivers reliable and controllable CO2 through the naturally occurring fermentation process. With safe, low-pressure operation, it is the most secure, simple, and environmentally-friendly aquarium CO2 delivery system available. With less than 10 minutes of maintenance and no pressurized cylinders to refill, you can have up to 30 days of CO2 for your aquarium without leaving home.

Solenoid Valve Included

This model includes a 12V solenoid valve, offering an extra layer of control not found in the smaller Bio-CO2 Pro systems. The solenoid valve allows you to automatically shut off the CO2 supply to your aquarium at night, when plants are not photosynthesizing and do not require CO2. This feature helps conserve CO2, extends the life of the CO2 production, and ensures optimal conditions in the aquarium for both fish and plants. Pair the solenoid valve with a timer (sold separately) for effortless, hands-off operation.

Instructions: 

1) Heat tap water to 80-85 degrees F and fill to the canister's interior fill line.

2) Add 1000g (4 cups) granulated white sugar (sold separately).

3) Add 4 Booster packets and 4 Activator packets.

4) Seal the unit, making sure the regulator is closed. Allow pressure to build up for 24 hours.

5) After 24 hours, you can open the regulator valve and adjust the CO2 flow into your aquarium.
