How much does CO2 injection cost per year for a planted tank?

A 5-lb CO2 cylinder for a 55-75 gallon tank costs $5-$20 to refill and lasts 2-4 months, totaling $30-$80/year. Equipment amortized over 5 years adds another $20-$40/year.

Is DIY CO2 cheaper than pressurized for small tanks?

DIY yeast CO2 costs $5-$15/year in materials for tanks under 30 gallons but requires weekly maintenance. Pressurized systems under $100 are available and are more reliable for consistent plant growth.
