*Sold*-Fluval 20g Co2 kit
I have used this co2 kit on my 5g tank for a while but recently upgraded to an automatic regulator setup. I have no need for this, so I am selling it. This is the simplest pressurized co2 kit I have seen. You turn on the valve and fill the diffuser every day. The diffuser simply traps co2 underwater (doesn't make bubbles). This includes 3 cartridges, the cartridge holder and the valve. You will need co2 tubing. the 3-pack of cartridges costs $18 alone. Asking $25 shipped.
