Can I daisy chain a phosban and carbon reactor together??

I have two 2lf`s reactors,one I use for GFO (low flow). and another I would like to run carbon in...
1 st ,The carbon has to be at what kind of flow(high)
2 nd ,If the above is true can they be daisy chained together, the carbon first going into the GFO (slowed down)then into the sump????
I would like to keep it clean looking and they will be fed from my return(mag 9.5)..
If this is possible or not, any info or suggestions would be helpful...8)

TIA

 

yes.. do it.. also put the carbon after the phosphate reactor..

 

oh and only control the flow going into the 1st reactor as causing back pressure on a reactor is never good..

 

really why??

Ok,,Yea I was only going to control the first reactor anyway though the other would just drain out......lol dont need to blow one up lol

 

So the carbon can help catch the fines from the GFO.

 

Ahhh after you said this,the light went off lol..gotcha, thanks...

 

If the GFO is first(w/low flow) wont the flow be to low for carbon??(was under the impression it had to have high flow)
also how much should I fill the reactor with carbon??

 

It is what it is. There are trade offs. Carbon does not "need" High" flow. It can just handle it. The flow for the GFO is going to be the limiting factor. First or last the flow throught the reactor will be the same. but since the GFO "need" the right flow to make it tumble, might as well have the carbon last to catch fines from the tumbling GFO.

The amount is going to depend on your directions. The GFO will last longer than the GAC. I am going to just put half batches in and change every two weeks. My carbon directions say to run 3-4 weeks. My GFO says 4-8. So I am simply going to try and figure out what two weeks would be and figure it that way. That is all I'm going by.

 

A little off the concept here, but in case you change your mind, here is what I went to for convenience and efficiency; Aquarium Filter Fluidized Bed Reactor: Magnavore Simplicity UV-Catalytic Reactor
I got mine without the sterilizer and pump. I placed mine in the bio ball chamber under the drip tray.

 

Everything I've read says GFO requires higher flow than carbon. You want the GFO to be slightly tumbling in the reactor so it doesn't cake up, carbon you generally don't want moving too much or it can break up and produce carbon dust which can get into the tank (not necessarily a bad thing but can cause problems in large amounts I believe).

Your mileage may vary depending on what exact products you are using (what type of carbon and where you get the GFO).

There's some info out here with some various types of each product:
