Thoughts on GFO in a media reactor

[Drewbaby]

I'm setting up my 125 and trying.to map out the equipment. Does anyone run GFO and what are the benefits?

The tank will be mainly sps

GFO is great for removing Phosphates from the water. It is very effective. I ran 6 cups of GFO in a reactor for the last 48 hours and dropped my phosphate level from .06 to less than .01. Probably don't need/want to start running it until your tank cycles and you have some livestock.

Tank is cycled. I actually just downgraded from a 180. This tank is all new but contents are old. The 180 was a used tank that I setup 3 years ago. Would it be better to run gfo and carbon or just gfo?

it would depend on your tank. If i was going to pick just one, i'd go with GFO to remove phosphates that enter your tank from feeding and such.
I run mine in a BRS Reactor.

I also run the large BRS reactor but I have 400 gallons. I run a carbon reactor as well. Carbon helps keep the water looking clear. I'd say GFO is a greater priority in my mind, but I'd do both if you have space and can afford it.

There's plenty of space in the sump and stand. My sump is a 40 breeder and after I'm done mapping out the equipment, I am going to the local glass shop and ordering some glass. That way I can build it.to suit the tanks needs.

So how often should I change the GFO? And roughly how much should I use at a time?

How much and how often are determined by your tank. There is a calculator on BRS which can get you started. If you have corals, go slow with GFO, you don't want to take down the phosphates too fast.
