    ive just built a 'rex reactor' , external diy . I will test it out in the next few days and post a comment.
    hopefully a bit more efficent.

    what type of filter are you running......?

    is there a reason why the return from a canister filter is not used to diffuse the co2.......?
    or are canisters too powerful for planted tanks......?

    this is my version, pressurized co2 and a cheapy powerhead i had lieing around. cheapest smallest diffuser i could find. all up, about $20 i purchased new.



    I run this on my 7gal.

    i use an up! atomizer on my 40cm cube. the diffusion looks a little similiar, but u dont get the 'spread' or cloud that the atomizer brings.. similiar sized bubbles, but less coverage...

    I reckon something like the one in this thread would be pretty efficient... While not the prettiest or least inconspicuous, it is certainly cheap and effective...

    I'd probably use a diffuser inside the reactor though, but that's just me being ocd...

    with Dupla type S and Dupla 400, what you have to consider is the tube size and whether you want to invest in more powerhead/external pump.
    If you use the Eheim Professional filters or fluval filters, some comes with 12/16 tube and the inlet of the splitter (the little plastic connector that supposed to go in between the filter to the reactor) only comes in 12 mm and 10 mm. 12/16 tube is too big for these unless you want to use a pipe ring to tighten the green tubes or if you can find a convertor. So something to consider.

    I'm using Dupla 400 and I dont think it's 100% dissolving the CO2 into the water because my indicator never turn green so I dont think it's a good one.

    Hope that makes sense.

    Yes, defenderzook, there are different types of CO2. Industrial, food and hydroponics are the three I'm familiar with.

    I disagree that renting necessarily costs more, khemo. It depends on how much CO2 you are using (based on filtration types & de-gassing rates), and how much a fill on a smaller bottle is costing you. I've run tanks (with trickle filters) that would use a 1.5kg bottle of CO2 in a 1-2 weeks. In those cases, renting was cheaper.

    The new-ish sera CO2 reactor is pretty good, that's what I'm using at the moment. Dissolves almost, if not 100% of the CO2 and is a lot cheaper than Dupla or Aquamedic.

    Renting will cost more in the long run.

    Also, have you tried simply renting a large bottle from whatever Gas company supplies CO2 (It is BOC gases here in SA... I assume that they would be in Tassie too). Make sure it's food grade CO2. Rental will cost you around $30-$40 per month for the bottle, plus about the same for a fill when you need it filled... but it will probably last you 12 months.
