It appears that the video has gone missing. Until I can find it and re-post it, you may be interested in Home Made CO2 Reactor, Do It Yourself CO2 Reactor Construction Details, and CO2 Reactor Modifications
Here is a video of my brand spanking new, already modified Carbon DiOxide aquarium reactor.
The water flows into the top in the big hose, which is coming from my external canister filter. The CO2 is coming from a pair of old juice bottles which have water, baking yeast and sugar in them. This all gets mixed up in all the splashing fun as it goes down the tube with the bio-balls.
At the end of the video you can see my little CO2 monitor in the fish tank – that little bell thingy stuck to the side of the tank. Blue means low CO2, green means good CO2, and if you notice it is more green then it is blue. This is even after the old method of CO2 injection was showing blue, and I hadn’t refreshed my Yeast Bottles yet. This new device appears to be more effective at CO2 Injection then the old feed-it-through-the-canistor-filter method.
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!
Here you can see the CO2 Reactor installed on my fish tank. I wanted it to be visable, so I mounted it right up front. I just think this gadget looks so darn cool!
More complete assembly details to be coming soon.
