My friend Matt flew in yesterday from Arizona. We ended up going to Big Al’s pet store. We where looking at the planted tank accessories, and noticed that they want $130 for a CO2 Reactor. We put one together for under $40.
A CO2 Reactor is a device used with planted tanks that will help push Carbon Dioxide into the aquarium water. Plants LOVE carbon dioxide. It is a major fertilizer.
Here are the $40 worth of parts I needed to make my Homemade CO2 Reactor. These parts include a couple of Siphon aquarium Cleaners, some Bio-Balls, airline tubing and couplers, and an Eheim Filter part I used for a water line splice.
We disasembled one of the aquarium siphons and attached the hose to the other siphon. These are Python brand siphons, they are fitted by compression – no glue, so just pull hard, they will come apart. There are enough bio-balls inside to completely fill the tube.
Here Matt and I are leak-testing the Do It Yourself CO2 Reactor in my bathroom. We hooked it up to my Ehiem Canistor Filter, ran it into a bucket of water, and turned it on. Can you believe? It works! Only a minor leak too!
More complete assembly details to be coming soon. .
