For Sale: Fluval mini co2 system

[Brookster123]

I have a mini system for sale, comes with 3 16oz. Cartridges. Full disclosure.. while it does deliver co2 through a diffuser it does need frequent adjustments, would be perfect for an office nano or any smaller tank that can be visited 5 times or so throughout the photoperiod. $ 19 shipped, i also have a bubble counter and diffuser for sale separately.

Still got it.. I've found it works quite well with the 45g. Cylinders, $9 at petco.
