    Does anyone have an operating manual for the Aqua-Excel calcium reactor?

    [​IMG]

    Failing that, can anyone clear up which is the inlet and which is the outlet above? I assume 3 is the CO2 inlet, but looking at the design even that I can't be sure of.

    1.inlet
    2.outlet
    3.from Co2 bottle
    judging by the pic.maybe a close up might help

    Here is a schematic of the system. Hopefuly this makes things clearer.

    Mek thats what I tought at first, but if you look at my sketch, It appears that the CO2 builds up under the top and then bubbles out of 2.

    However if you make 2 the inlet - the compression fitting seems to point that this is so- then inlet water and CO2 could get to outlet (1) before going through media- or is that neglegent, compared to flow through reactor pump.

    Or should 2 be the inlet, 1 be the CO2 inlet- thereby ensuring CO2 goes through media and 3 is actually the outlet back to the tank. But then the bubble counters, flow monitors don't make sense

    Thalion, see my reply/ concerns to Mekaeel. Are you sure that is the way to connect?

    I see what you are saying but the needle valve is usually used to control the OP, but in this one it looks to be the IP. The needle valve usually controls the drip rate, so if you control the IP you should be able to control the OP. Run it with a bucket of water and see what happens.

    No Mek, bought it off Regal about a year back for a tankI was inteding to build. Scrapped that idea and instead using it on a frag grow out tank in a fish room I'm setting up. Will chat to him when he gets back from IMACSA.

    Thalion so you saying that the needle valve normally regulates output flow? If that is so it would be opposite of what Mek said above, and the way I had it hooked up originally. I'm actually leaning that way myself. Intuitivley I think the compression fitting would be intended to be used on the supply pump inlet.

    To restrict the flow leaving the reactor is sometimes not wise. The resultant pressure increase in the reactor could cause leaks. Its always best to restrict the flow entering...

    At a glance i would say
    2)Outlet
    3)co2 inlet obviously
    1)water inlet

    seems right to me

    Why would they put a high pressure compression fitting onto the outlet side, which simply has a short piece of pipe leading back to sump with no pressure at all. The inlet, however coming from the feeder pump ,and as you say under pressure, is simply connected by a push fit over a tapered nipple??

    Mistake perhaps by the person who took it out the box.

    I would say 2 is the outlet as that is where you control your drops p/m that flows into your system and would be under pressure.

    Alfie in that case don't you mean 1 is the outlet? There is no control mechanism on 2. It is just a pressure compression fitting.

    Nope. The photograph above was taken from manufacturers websight. Mine is set up exactly like that.
