    DIY ozone reactor :)

    Hi everyone,
    thought I'd share my experience in building a DIY ozone reactor.

    first, here is what you will need.

    mag7 pump,

    kent injector ( or make your own 3/4" to 3/4" a 1/4" nipple in the middle.

    100feet of 3/4" flex pvc ( either the clear or white stuff ) warning, do not use the regular tubing used on aquariums as it will most likely crack and leak.

    a container to hold activated charcoal.

    a ozone generator ( I have a 300mg/H unit )

    bunch of fittings.


    ok,

    Hooking up the mag7 to the tubing:
    mag7 is 1/2" thread male needs to be connected to the injector.
    I took a kent 1/2" and added a 1/2" union in between them.
    then from the injector added a 1/2" true union ball valve.
    the other side of that ball valve, I converted the output to 3/4" and installed a barbed 3/4" end to fit the flex pvc tubing.

    Making the charcoal filter:

    I cut of a piece of 18" of 1-1/2" wide hard pvc.
    then I drilled with a fine bit a hundred tiny holes in a 1-1/2" endcap and glued it on the 18" hard piping.
    I then took a 1-1/2" union and glued it on the other side of the 1-1/2" hard tubing.
    so one side is the endcap the other is the union.
    I then used a few fittings to drop from the 1-1/2" union to 3/4" barbed male connection.
    took apart the union and filled the newly built container with activated charcoal.

    Now, hook the two sides of the 100 feet tubing, ( one to the mag7 setup the other to the charcoal container.

    hookup the ozone to the injector.

    ( prior to this you should have rinsed all plumbing and charcoal )

    fire it up and use the ball valve on the mag7 to determine the flow on the output, it should take ~45-50 secs to reach the charcoal setting.
    This has been determined as being optimal by an article published on Reef Central.

    The reason for the 100 foot tubing is contact time. Most ozone systems out there have barely a 5-10 sec contact time ( just like hooking it up to a protein skimmer ). Hooking it up to a skimmer is not safe as the ozone could escape without being filtered by the charcoal & since most skimmers are made of acrylic, not a good idea as ozone will weaken the acrylic. Also, skimmers have a faster turn around time then needed for ozone to do its job properly.

    The reason for the charcoal is it seperates the ozone oxygen.
    o3 -----> activated charcoal -----> o2 + o
    making it safe again.

    doesn't look tooo pretty.. but it works great

    I'll post a pic later on.

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    here is a pic of the parts.
    the reactor is now setup behind my skimmer so can't really take a pic anymore.
