    Hi Guys

    I have converted an calcium reactor body into "generic" reactor.
    BUBBLE-MAGUS - Aquarium Internal skimmer|external skimmer|Dosing pump|Calcium reactor|Nitrate reductor/NO3 reductor|Filters|Turtle shell lampshade|Water monitor and controller|Additives|moonlight LED

    One will be running Activated Carbon and the second one NP Pellets.

    I have replaced them with 10mm attachments.
    I will play with it a little more, I might have to go up to 20mm for the NP reactor, the pump will be adjustable 1200 lph.

    So here is the newly opened reactor

    Here is the moded outlet

    and moded inlet, the 10mm pipe just screws in with a washer and bulkhead, no changes needed.
    [​IMG]

    Here is the concept for the NP Reactor
    [​IMG]

    Notice the down pipe like a TS skimmer, this will force water downward creating a more even distribution of flow, it will also help with possible "back-washing" of pellets.
    There will also be a smaller "cup" at the top with kind of a bubble-plate to prevent pellets being pushed out into the system.
    I will post step by step picks as I get the rest of the stuff.

    Total cost of project R1760, excluding pumps :)

    Awesome mod, well done.
    In regards to your N/P Reactor I would suggest that you have the outlet in the body pointed at an angle to swirl the pellets as you will be losing pressure with the outlet pointed down like that

    Thank you for the input, I reckon I will try a couple of different ways before hitting the sweet spot.

    I cant wait!!
    I have to collect the rest of the parts for the NP reactor on Saturday.
    The carbon reactor is already up and running :)
    I ended up using waaaay to much activated carbon..........the whole packet :whistling:....about 6 - 7 large cups...well mug size.

    SO here goes, all done, now I have an Activated Carbon/Generic reactor and a DIY NP reactor well....more a MOD.
    It took 10 hours to make....I wont lie it wasn't easy, all the work was done with a Dremel.

    You can see it is 15mm and 20mm connectors, I later changed it to both be 20mm way better performance.
    [​IMG]

    in this pic you can see the original inlet, I used a small rubber cap from a venturi to block it.

    And here it is in action with 500ml of rice for testing.
    The pump is the a Hailea pump (2500l/ph), unfortunately I only had a OTP 2000 needle wheel impeller, you can imagine the performance increase if I used a regular impeller.



    ps. if you have the correct tools, like a bench grinder, this job would take 5 hours :)

    I am also upgrading the Carbon Reactors inlet and outlet, to 15mm elbows, it is currently 10mm, I dont think you need too much movement with Activated Carbon.
    I am thinking of mixing Activated Carbon with Phosguard in the future, I read on other forums that some guys do this.

    very nicely done.. i have some changes i need to make to My Skimz FM100 reactor.. i wanted to increase the diameter of the pipes from 10mm to 20mm to insure more flow but cracked one of the seals on the elbows..

    a dremmel looks like a nice tool to have for these kinds of mods.. guess im going to have to get me one..

    add a one way valve on the reactor inlet downpipe.
    So that when you switch the pump off, that it does not syphon smaller particles back into the pump.

    That is the next addon :)

    I will also be removing the bottom plate and adding a modified end-cap on the pipe.
    I will then make angled cut outs or drill holes in the end-cap, this should increase flow big time.

    I have also converted my Reef Octopus extreme 200 external to be internal, it has a spare inlet, I will be making an attachment for the NP reactor to pump directly into the reaction chamber (well the reaction section under the bubble plate) using this second inlet :)

    Dude totally get a Dremel, I suggest the 300 series http://www.dremel.com/en-us/Tools/Pages/ToolDetail.aspx?pid=300+Series
    Then go to builders and get one of their generic bit sets...paid like R99 for 50+ pieces.

    I am glad to report that I have changed the 10mm inlet and outlet to 15mm on the Activated Carbon reactor, it now has a slight tumble, it loosens up detritus nicely and is pushing a sh!t load of water :)

    If I did it again, I would use the 15mm bent elbows from the start it would also be cheaper as it takes less parts to build it with 15mm, also less hassle.

    I imagine I could fit a bag of Purigen or Phosguard or both on top of the Activated Carbon, it definitely pushes enough water through and there is plenty of space for it.

    The NP Reactor on the other hand is just waiting for NP pellets.
    I left the rice in, standing for 3 days....OMG it stinks...smells like rotting meat soooo gross.

    my personal opinion is that carbon should not tumble you will be grinding it up tumbling it

    yes agreed, it should just allow water through without tumbling. Else it will grind itself into small pieces that will eventually escape the reactor. Into your tank.

    it could tumble but then i would advise fitting a strainer plate (like on the pellet reactor) to avoid small particles escalping...

    i believe the more media moves the less dirt (no matter how little) it will capture..

    Correct if it was tumbling it would grind, this is more like a boil...kinda like pap on a stove, and it is erratic, so not focused on one place, the "boil" moves from place to place very slowly, I will upload a clip tonight.

    I have the second plate in already ;)

    Thank you for all the input guys!!

    Does anyone know were I can get my hands on some NP pellets, in Cape Town?
    I found one place but R480 for 500ml seem a bit much?

    Going to pick up a bag today, I have the day off...want to finish this project.
