I installed the QANVEE CO2 diffuser outside my planted tank and noticed a significant improvement in plant growth. The tank looks cleaner with no visible equipment inside. It’s easy to clean and the CO2 dispersion is very fine and consistent.

The diffuser fits well with my existing canister filter. I appreciate that it doesn’t clutter the tank. I’ve cleaned it once in two months and it still performs well. The ceramic tube replacement is straightforward.
