    David, Remember the T when you try to prime your filter. You'll see how necessity is the mother of invention that lead to the 30 second water change system. Click the hose in, turn the valve and the lemon tree gets watered (best crop I've had in years with PMDD ferts lol). Then click the hose outside to the tap, turn on a smidgen, throw the declorinator in to the tank and don't fall asleep while you watch it slowly fill..... Literally 30 seconds effort. It used to take me over 4 hours with a gravel vac and a small wheelie bin and then used a 10 litre drum with a tap on it to do a 50% water change on my big tank.

    Disco Frank, clean what? It's an empty pipe....... I've had mine to 10bps in my 20"x100mm with 100% dissolution of the gas. The drop checker was yellow. When I gassed my fish once when I started to adjust the bubble rate and the door bell rang, the bubble counter was a jet stream and still nothing was coming through the spray bar. It's a balance between flow of the filter pump and the length of the reactor. So far, the sizes that work are as follows: for the FX5 and the Aqua one 2700 lph nautilus 20" x4" is fine. For a nautilus 1400 a 15"x4" is fine. Same for an eheim 700e, and the worx 1200. Let's just say that if you make one at 20" tall you're covered up to 3500lph with a 4" width. I will be testing the 6" wide version I made for the 6 footer when the solenoid arrives. Im thinking maybe 12bps will be easily dissolved without any flow through. I will be making one for AXL for his 9 footer at 5000lph flow so I am doing the development work now, I'm hoping by going wider it won't need to be 40" tall.

    I dont clean my atomiser :P its is slightly green but works fine under my inlet
    no idea how much co2 that is going in, i think it needs more
    struggling with bba, i did just turn the lights down another hr
    I do think i will need to build a better reactor similar to yours, who knows

    For BBA, you should increase your CO2. No point in reducing light especially in a tank that is deep. I am surprised that the atomiser works without clogging. Perhaps in the shade, there is not much algae.

    Disco, totally agree with Rebel here. Siamensis will help too. When I used atomisers they always clogged after 2 to 3 weeks and they were right under the filter inlet too. The best diffuser method I found was using a one inch long piece of 5mm bamboo skewer (the thicker ones - woollies have them) jammed half into the co2 line and the other half shaved and wedged into the filter inlet. Its not as effective as a reactor but it saves a load of cleaning over the ceramic diffuser.

    Disco, start a new thread for your BBA. Keen to see how you progress. Is it for your 6 footer?? SAE (if you starve them) will demolish already established BBA. Otherwise it will 'never' go away unless you nuke it with H2O2 or Glut. I've got three SAE and they removed ALL traces of BBA within one week.

    Default Final commercial version launched.

    Commercial Version Launched : following a year of R&D and input from members here, we have a final commercial version. After playing with a 6 inch wide version in the "Brilliance with brilliance" journal I realise we now have the ultimate reactor. This is the first one I have done for another member. Design thoughts focussed on making a reactor that would meet the brief of a 3000 lph pump, plus also ensuring it was future proofed should the owner wish to upsize in the future (or downsize). So, what I came up with was to make the reactor as per usual out of DWV piping for strength, 500mm high, 25mm tank fittings, netta 25mm male to 25mm female elbow to make it easy to change out the barbed directors to different sizes in the future. It also uses a 25mm threaded riser tube inside same as the first version I did to maximise flow. All future units sold will be built like this to give the owner maximum flexibility and comes supplied with injector nozzle and all clamps required for installation, plus a detailed diagram and step by step instructions on installation. New special paint that adheres to plastic has been used as well. Thank you to grubs and all others who have assisted with their input. Here it is, the final product:

    Very nicely done Pete. What is the projected price? Now go and make one in clear perspex or polycarb. It will be a lot harder to source the required end caps etc.

    Thanks Vlad. I can get a polycarbonate or abs plastic one made in China if I need to. An associate of mine gets gear from there regularly and has offered, but this way it's versatile, drop proof and I know what's in it. Price is $150 plus P&H. There's about 4 hours work in it incl time at suppliers picking up parts and I pressure test each unit.

    If your needing to use a special paint to adhere to the plastic, this might be easier or could just be what you're already doing, just rub the outside of the pipes with some grey scotchbrite, spray with a plastic primer, then spray your black top coat on top of that this will ensure the paint wont chip off easily or peel.
    Any fin is possible if you don't trout yourself!

    Thanks Josh. That's an idea I might try. I'm using a paint specially developed to adhere to plastic without primer. I've used it on two of these units and an external heater build and so far there is no peeling at all. In fact the finish is so good, I look at my own and think they look crappy lol.
