diy inline co2 reacter advice


Hi all

I have just built an inline co2 reactor and attached it to my eheim 2213.

Firstly i tried it in between my filter exhaust and my spray bar, i tried blowing down my co2 line to make sure there wasn't any blockages and it seemed difficult to blow air in against the pressure of the pump.

Next i tried it on the inlet side and this caused problem with an air lock in the tubes.

Anyone got any advice on what i should do?


Thanks

Dan

Are you using pressurized co2? If so, you just need to set your regulator to 10-20 psi and it will be fine. It doesn't matter what YOU can blow...

Thanks for the replies. I'm am pretty sure it is running ok now on the inlet side at a slight angle.

I have just bought a 240L jewul tank and will be setting it up when i move house in a couple of months and want a more to build a better co2 system for it. what the best option for a diy pressurised system? i have read a bit about fire extinguishers and they seem like a good way to go but how long would you expect as tank to last if was only on for 10 hrs a day?

Any advice on diy tanks and regulators would be great

Thanks again

Dan

I would watch your pump carefully. Being on the input side, you do run a risk or losing your siphon. With diy co2, it shouldn't be a huge issue but it still might happen. I would put the reactor how you had it, on the output side. Don't worry about the pressure. When you turn your filter on, then there should be little to no pressure to cause any blockages.

Since you are in no rush, piecing together a pressurozed system might be cheaper than a prebuilt one. Constantly check ebay. There's a bunch of surplus dual stage regulators and needle valves that will work for our application. Shipping might kill you if you can't find things from your part of the world.

You could save yourself some trouble and get a prebuilt system. I prefer the guys at sumoregulator but there are others like gla and rex. You can get a really good regulator for around $200. Then all you need is a co2 tank and diffuser/reactor and you are good to go.
