  • What should I try now?

    Hi Guys,

    For the last 2.5 months I have been running an AM1000 + DIY needle wheel connected to spray bar. I maxed out the AM1000 (i.e. pumped as much CO2 into it as I could without setting up a constant cycle through the dual venturi line) and also continously upped the needle wheel until I obtained good results. All plants generally doing well.

    But - my 6.8kg bottle (15lbs?) has just run out. 2.5 months is ridiculous though; what a horrendous waste of gas (probably mainly due to the DIY needle which was really cranking it out). At least I gave it a decent go though.

    Now I'm not sure what to do next. ;-)

    I know I should be able to get good results using much less gas. Surely I should be able to get 6 months+, my tank isn't that big, and the lighting is low.

    For the moment, I am going to go back to using the AM1000 exclusively. I have pushed everything down as low as possible in the tank, as close to the substrate as I can get, so as to absolutely minimize surface movement. The fish are fine.

    The details of my tank are:
    Tank: 72" x 18" x 15" (a little under 100g I think)
    Lighting: Only 120w of T8
    Fert: EI for 100g

    Any suggestions most welcome!

    Scott.

      And, testament to me challenging my 'Guru Class Expert' status above, I put in the wrong tank specs!

      My tank is 72" x 18" x 20" - so that's a total volume of about 110 gallons?

        I'm just using AM1000's on my tank at 40 ppm of CO2 and I'm doing fine. I tried it for some time, but I went back to just using the AM1000's. I just use half the amount of CO2 as before and I haven't seen any difference.

          ....and your tank looks awesome dutchy. Based on your experience with the external reactors, do you think I could get away with a single one on my size tank? I have tried in the past and it sort-of worked - maybe I just wasn't doing it right?

            I think a setup like mine would be better. There's not that much difference in tank size (72 x 22 x 24) Of course AM says their reactor is sufficient until 250 gallons, but that's only with average CO2 levels like maybe 20 ppm.

            (You can't run two AM1000's on one CO2 regulator valve, you need a dual valve)

              Do you use the 'dual venturi' mod on both the AM's or do you just leave the bleed value closed?

              I think you said you are getting about 3 months per bottle of CO2? I can't remember the size of the bottles?

              I just have a single 15lb.

                I have the bleed valves closed. I have two 2 kg. bottles that together last me around 3 months now.

                  Ok, so your gas economy is 4kg per 3 months (i.e. a single 4kg bottle with appropriate regulator would acheive the same thing).

                  My tank is smaller and using the misting method in conjunction with a single AM1000, my economy was 6.8kg per 2.5 months (I know I already said that at the start of the thread). ;-)

                  The economy is more important for me than the simplicity, so I think in the reactor vs misting debate, I am shaping up to be a reactor person. ;-)

                  I will give the single AM1000 another go, say for 1 month on my spare 2kg bottle. There is only so much CO2 I can crank into the AM1000, as you will probably know, before the gas starts building up (or churning through the venturi line constantly if it is in that mode). If I max it out and don't get the result I want, I suppose there is no doubt about it, I will need a second AM1000?

                  What's your typical water temperature?

                  P.S. If you use the dual venturi mode, i.e. open the bleed valve and feed it back through the input of the pump, could you slightly improve your gas economy?

                    ... I forgot to mention that it would seem almost pointless to try the AM1000 on it's own again when I ran it with the DIY needle wheel; but what I have done this time is moved the AM1000 outlet right down to a substrate level spray bar and have reduced the surface movement so that the surface is almost dead still. I am watching the fish carefully of course.

                    I am going to try to squeeze the absolute best possible performance out of the single AM1000.

                    Do you think I could sling a second one on an Eheim 2217 if need be?

                      This is just my personal experience, but I've actually gone from needlewheel to reactor. One benefit that I've noticed off the bat is with the needlewheel I was running 5-6 bubbles per second to get a lime green drop checker, and with this reactor I'm running 1 bubble every two seconds and have a yellow DC. My CO2 tank just got a seriously extended life.

                        Exactly!

                        I'm going to keep my DIY needle wheel handy though. In the event that my reactor leaks, reactor pump conks out, or something along those lines, at least I can stick the needle wheel back in and use it for 'emergencies'.

                            If you max it out you will need a second AM1000. I never max them out, logical, because the working load is divided by two.

                            In the dual venturi mode the gas economy was worse. The mist flowing into the rector was already so fine that the reactor could not make the bubbles smaller. They passed like if the reactor was not there.

                            Connecting another AM1000 to an Eheim 2217 won't give you al lot of flow, maybe no more than 400 liters per minute (100 GPH). Anyway a setup like that was enough for my previous 50 gallon tank. That's almost half of yours. So maybe it's enough. Try. You can always change it later.

                              My understanding is that that is the intention; misting later in the day when the CO2 will no longer disolve as readily. Are you sure the gas economy would be worse? Using the dual venturi mode would help dissolve bubbles faster earlier on, would it not? Have you tried it with your current setup? Perhaps try the pH controlled on in dual-venturi mode?
