In setting up my frag tank and future aquarium, I’ve accumulated quite a bit of equipment. I scoured ReefCentral for good deals, and for some reason I’ve been crazy for calcium reactors. Initially, I was going to have a 225-gallon aquarium so I found and purchased a GEO 624 calcium reactor. It is rated for approximately 400 – 450 gallons. Then I decided to downsize the tank slightly, to about 187-gallons, and fearing I would have constant pH issues with an over-sized calcium reactor, I decided to downgrade the reactor as well.
I was able to find a brand new GEO 618 (rated for 350-gallons) for a steal. I got it, then had a few setbacks with the main aquarium…that being not having one and postponing it a little while. To quench my aquarium needs though, I started the frag tank, which is approximately 80-gallons. A week ago, I found a good deal on a Deltec calcium reactor, again on ReefCentral. I had always wanted a Deltec reactor, since they have a fluidized design which uses less CO2, and of course I purchase it. This Deltec is a PF601 is rated for over 500-gallons! Needless to say, I will not have issues keeping the calcium levels elevated. But now, this leaves me with a GEO 618 to put on an 80-gallon frag tank. I guess I’ll just have to stock both aquariums to the max with hard corals.
