Geo or MRC?

I'm leaning toward the Geo calcium reactor. Anyone have a personal preference which they can support with facts.

What size water volume are wanting to support? Tank+Sump+refugium?

Presently 90 gallon tank with a 30 gallon sump, however I see a 180 gallon tank in my future with at least a 55 gallon sump and a 40 gallon frag tank attached.

I have a GEO and like it for it's simple operation and very consistent output. I'm running it on a 90 with a 30 gal sump. For your application I would recommend the 618. I am running a 612.

Thanks Henry. Simple operation sounds like a good thing to consider.

I ordered a GEO back in January and I am still waiting for it. I sure hope it's worth the wait no will say when I might see it.:confused:

I have an MRC-2R reactor now, I have had to modify it to raise my alk levels, and too keep it from wasting CO2. They are built well. I believe there is room for improvement. I am in the process of upgrading to a custom reactor.
