Hello to you all. first of all i should say that i am a new SW keeper as well as a newbie to this forum. I currently have a 38G FOWLER (would like to slowly add a few corals and eventually upgrade to a 75G). I have bent Ron's ear more than once at Jo-Mars and now I would like to bend some of yours. My current delima (sp?) is whether to upgrade to a wet/dry sump or go ahead and do a refugium? I am currently using a hang on with a CSS 65 skimmer. Also, how big should it be? Should I or can I go ahead and make it large enough to accomidate a 75 if that is the ultimate plan????? Thanks ahead of time for the input.
