I have a 210 SPS tank that I have been using a DIY calcium reactor on. I'm sick of all the problems caused by my poor DIY job and I'm going to go with one the pros make. Any opinions on which would be better between the MRC CR-2 vs. Geo 618? Both look like good calcium reactors. The footprint isn't really that big of an issue. I like having the dual stage reactor for the MRC one, but is the GEO worth it? Any opinions welcome. Thanks.
