Colombo CO2 Advance Refill Bottle 95g

The quick-connect fitting snapped right onto my existing setup without any fuss, and the 95g refill has been steadily dosing my planted tank for weeks now.

My old canister ran out mid-week, so this 95g refill was a lifesaver — screwed on perfectly and got my plants pearling again within an hour. The pressure feels just right for my small tank setup.

My CO₂ was running low, so this 95g refill was exactly what I needed—it screwed right onto my existing kit without any fuss. Works perfectly with my setup and seemingly lasting just as long as the original. Glad I could get a simple replacement without buying a whole new system.
