I took a little different approach to building my own DIY CO2
reactor. Since I didn't want a bunch of plumbing hanging off the back of the tank and none of the reactors I could find on-line would fit into my 10 gallon low-light tank, I decided to get creative and ended up with the little gem in the picture.
comes from the generator bottle (also DIY
) via a seperator (Again DIY
) and enters the bottom of the reractor tube which was made from scrap UGF
riser tube. Water is pumped in by a small fountain pump I got at K
-Mart (garden section) for all of $17.99 and enters through a button drip emmiter that I had removed the insides out of. The reactor is held in place by a couple of heater holders. It's small, easy to hide in the tank, and most of all it's effective. I used a straight pin to punch some small holes in the side of the body to keep it from overfilling with the CO2
. Excess gas simply flows out of the reactor to the surface.
