So, I decided to purchase a gfo/carbon reactor. I am wondering if I can buy the BRS deluxe version single canister and run both carbon and gfo in the same chamber?

It is a 69 gallon tank and i’m concerned about space for the dual chamber one. Just want to get my nitrates and phosphates down to reasonable levels and have the added benefit of clearer display.

I can accommodate the dual canister model but it will be tight.

Appreciate all of you.

Gut this from BRS. Decided GFO not for me and abandoned the idea.

Mixed.

Container size based on how much GFO needed plus the mix of carbon required. Caveat being just like with any mixed bed resin. Consumption of one might be premature waste of the other.

I think you would want the gfo to tumble a little bit but definitely not the carbon.

so what’s the consensus? One chamber with both or have a canister for each media? I think that if i have one for each, i could run the risk of stripping all my phosphate and nitrate completely. Maybe one chamber with both will give me a perfect balance?

If you run it separately, you want the gfo to tumble slightly and that may grind the carbon. If you mix it together, the gfo has less of a chance of clumping. I run two chambers, pack the carbon and let the gfo move a little. Use a little gfo to begin with and see what effect it has on the phosphate and adjust from there. Neither gfo or carbon is going to have much of an effect on nitrates, you won’t strip it out. See how the tank does, you won’t have perfect balance by chasing numbers. Do what is best by looking at the tank. Go slow!

You have to ask yourself how will you replenish one without wasting the other. GAC could easily last for weeks but GFO only for days.

If you look at the SpectraPure dual reactor you’ll see that the water flows down on the carbon and up on the gfo. That way you can control the flow to each chamber.
