    Can you run media in a mesh bag with this product?

    Bulk Reef Supply Hey Jared,
    There isn't any reason you couldn't though most medias would be best served just placed in the reactor without a bag.

    Would this reactor work well with GFO?
    I am thinking the GFO will pass right through the strainers.

    Bulk Reef Supply Hey Ron,
    It does work pretty well. The reactor is an upflow design so the GFO is generally being pushed away from the strainers. When the power is off or your unloading its not unusual for a little to fall below but it doesn't hurt anything there and really nothing to worry about.

    what pump do you recommend with the Reef Octopus Media Filter 4" Chamber running gfo?

    Bulk Reef Supply Hi Lee,
    A mid range pump would do the trick here. Something with 300-500gph of flow with a bit of power assuming your not running the tube 40ft or anything unusual. The danner mag drive 5 or the sicce syncra 2.0 would both be great choices.

  • Great product By Bob g on 3/9/2014

    I am using 2 pounds of media (75% rox .8 carbon / 25% gfo), i just cut a blue and white filter pad i picked up locally for above and below the media to prevent grinding, paired up with the cobalt mj-1200 powerhead ( cant even hear it when i sleep) . Very well made, stands 21 3/8 inches tall, bout 54.5 cm, you will need 12 inches wide at the top, 7-8inch by about 6inch at the base, you can use soft silicone tubing with the plastic clips sold here if you double up the tubing (about a one inch long piece cut down the middle and a 3/4 inch piece an inch long to fill the gap, use large pliars to secure clip. Glue in barbed fittings with pvc glue (dont forget to use the primer) very easy. Water may be too clear now haha, every time i stare in my tank from the top i get my nose or beard wet.

  • Great Reactor Just!!! By RacinRevo0818 on 1/14/2014

    Works great but the only problem I see if maintenance on this.. It is practically seal with the only access thru the top. It doesn't come apart to clean the screen. It looks like if you had a 2 foot extension you could possible take it out for cleaning?

    Also as noted above you have to have large media, Carbon Rox seems to be to small to use. It works in there but doesn't work well..

    Would I buy again? Probably not, would get one that is easier to clean.
  • Works great By Marcus on 10/2/2012

    My water looks amazing with this running and it also helped keep my numbers at zero since i leave the Carbon in for 3-4 weeks before changing it out and i have a huge BIO load in the tank.. Just make sure you buy the larger Carbon since the small grains will clog the reactor and end up in your sump i tried it and it doesnt work
