FAQ

Why do planted tanks need CO2?

Plants use CO2 for photosynthesis. In low-light tanks, natural CO2 from fish waste is sufficient. In high-light tanks with dense plants, supplemental CO2 increases growth. Typical target is 20-30 ppm CO2.

What is BPS (bubbles per second)?

BPS measures CO2 injection rate. 1 BPS = 1 bubble per second. Typical rates are 1-3 BPS for small tanks, 3-5 for medium, 5+ for large tanks. Adjust based on plant growth and CO2 levels.

Is the CO2 calculator accurate?

This calculator uses standard guidelines for CO2 injection. Actual needs depend on plant density, light intensity, and water parameters. Use a CO2 test kit to verify levels.

What CO2 systems are available?

Options include pressurized cylinders (best for large tanks), DIY yeast systems (budget-friendly), and liquid CO2 (convenient but expensive). Choose based on tank size and budget.

Is CO2 safe for fish?

Properly dosed CO2 (20-30 ppm) is safe for fish. Excessive CO2 (>40 ppm) can harm fish. Monitor pH and CO2 levels. Use a drop checker to verify CO2 concentration. Ensure adequate aeration.
