(Re)-setting up a marine tank. I loved my last one (a 30 gal Marine w/ inverts and live rock), and was very attentive to it, and it turned out great. But a few fish got Ich, and I just got frustrated (happens to A LOT of marine tank hobbyists). But I've purchased a 90 gal. (A long time ago), and REALLY want to get back in to the hobby. I loved it, and was good at it. But it IS expe$ive, and time-consuming.
