Dual Media Reactor?

[Tristan]

So basically all this is, is a regular media reactor with 3 sponges in it.
The bottom part will contain carbon and the top part will contain GFO if that makes sense.
Since the carbon has to be immobile and the GFO has to be mobile and if the middle sponge were to fall and the carbon was in the top part and the GFO was in the bottom part then it would cause the GFO to become immobile.
If that makes any sense.

So the bottom and middle sponge would hold the carbon in place.

And sorry if the bottom sponge looks confusing. It is actually going to be all the way on the bottom not suspended.

The middle sponge will be holding all the GFO and the top sponge will be all the way at the top to prevent you know… the GFO from escaping.

1st option just mix small amounts of gfo and carbon mixed together that will keep the gfo from binding. Every 2 weeks remove and replace. 2nd option would have gfo directly on bottom no sponge then enought space for gfo to tumble then a sponge, carbon and another sponge at very top packed so it doesnt move. The water movement should hold the sponges and carbon up high and keep the gfo tumbling. You can remove the carbon on top and clean the sponges every couple weeks and keep the gfo in use until it no longer works.

Oh okay. Thanks. I hadn't thought of doing that.

I think GFO and Activated Carbon have different tumbling requirements. Your design would work but in my opinion it is not the most efficient way to utilize the media.

Would the amount of media used really be enough to really make any difference?

The reactor is going to be used on a 10 gallon tank.

For GFO you are supposed to have a slow tumble as where carbon it is not supposed to tumble at all. It's a very tall reactor so there is enough to put both media in.

I mix 1/3 GFO and 2/3 carbon and keep them tightly packed so there is no movement. This ratio was recommended to me by BRS for use in their reactor.

The reason for me thinking of this cause I didn't want to do that. I didn't want to mix the GFO and carbon

I just added 2 filters top and bottom and carbon on bottom gfo on top the duel filters help with the fine particles I use a coarse filter then fine its helped allot
