Jason submitted a new Article: How To Build A Cerges Co2 Reactor Read more about this article here...
For those interested in building one this is the shopping list. 1 x 10" Water Filter Housing with 3/4" Brass threaded BSP Ports and a Pressure Release Valve. 1 x 1/2 Inch 90 Degree Tee BSP Threaded PVC Pipe Fitting for the co2 hose barb 2 x 3/4 x 1/2 Inch BSP PVC Reducing Nipple Pipe Fittings to reduce the 3/4 housing ports to 1/2 fittings 2 x 1/2 Inch 90 Deg Elbow BSP Threaded PVC Pipe Fitting for the filter hose barbs 1 x 1/2 Inch Hexagon Nipple BSP PVC Pipe Fitting to connect the elbow and tee 2 x Hose Tail End Barb Connector - Hose Internal dia (Bore): 12mm (1/2") BSP Thread size: 1/2 (for the filter 12/16mm tubing) 1 x Hose Tail End Barb Connector - Hose Internal dia (Bore): 5mm (3/16") BSP Thread size: 1/2 (for the co2 tubing) 1 x Hair Bun Sponge to place around the internal piping and help break down the larger bubbles (is this needed? we will see) i will also need some piping for inside of the housing that i will add to the list once the housing arrives and i know what size i will need. PTFE tape.
Jason That looks very Hi Tech for me but I am positive it will help others. Over all it looks very professional and certainly not looking like a cheap DIY. Is there a market for them? Keith
Thanks Keith More and more people are starting to use them. They are almost 100% at breaking down co2 unlike in tank defusers. Co2 that is still in the form of a bubble is not used and wasted co2. So at the end of the day this means to reach the required 30ppm of co2 in a aquarium it will require less co2 meaning the co2 in a bottle will last longer saving money in the long run. Another option is a in line defused that is not 100% and costs £25 but lots don't last and a new one is needed, 2 x £25 is more than this cost to make. These are also more affective in larger aquariums. Over the year this will pay for itself with the reduced cost of co2
Cerges CO2 Reactor - Revision 2 Revision 2 why? because i wanted to create something that was even better at breaking down the co2 and from reports the original way can result in gas buildup. I've now reversed the in and out so the water and co2 come down the center tubing mix at the bottom and then up to the top of the reactor. Revised version 2 I've now reversed the in and out and also added a center from a old sponge filter that's very similar to a filter intake strainer. also using a clear tubing instead of the white one i previously was going to use. The end of the strainer fitted the bottom of the filter perfect testing will happen asap once ive setup my co2 on the tank, ill be using my Eheim Professional 3 250 Filter - 2071 instead of my classic.
Hi Jason, Great Build Lucky the filter bit fitted so well Nice when a plan comes together ""As Keith Said"" Its a professional looking unit. Hope all go's well when running the test.
Thank you both it seems a lot of work for co2 but hey i enjoyed the build, no in-line diffusers, in-tank diffusers, less in-tank equipment etc hopefully no 7up bubbles in the tank meaning the co2 has fully dissolved and will require less of a bubble rate saving money in the long run i plan on setting everything up in a couple of weeks and then ill start another journal
Hi Martharing welcome to GBG Thanks, I have now installed this and so far so good Here is a quick photo I took with my phone to show it installed.
Revision 3 will include some changes and a up inline atomizer im just experimenting for the best results.
Jason I can understand all that very easy, water in, through a strainer and out again. Unless I am mistaken could it be done using a quality canister filter? Keith
Keith if you placed it inline after your main filter it might work but into your main filter ive heard it causes a gas buildup and burping? Ive not tried it myself.
