I've been reading for a few months now and even registered a while ago, so I guess it's about time I got around to introducing myself. I'm Dave, and I'm one of those "in and out of the hobby over the past XX years" types. In my case XX= almost 25, I started with a 20H FW tank in the late 80's and by 1990 I had a dedicated "fish room" with 12-15 tanks at any given time (including several FW, brackish, Rift lake and a couple SW). The focal point at the time was a 55 gal reef (or, what passed for a reef in 1990).
When I moved to a new home in '94 I kept only the 20h FW tank and the 55 gal, The wet-dry was a casualty during the move so the tank was set up as FOWLR this time.
I got married and moved again 5 years later and the tanks ended up in storage until I took my son to see "Nemo." Within a few weeks, the 55 is a FOWLR again with a couple of clowns, a few damsels and a few snails and hermits.
Fast Forward a few years and the last fish has gone MIA, tank is still running just to keep the LR alive. I've changed bulbs every now and then (VHO gave way to PC during the Nemo days) and done the occasional water change, but I haven't come close to keeping up with it the way I should.
A couple months ago it dawned on me that "I bet I could get that tank back to it's former glory with a bit of work and maybe $200-300 in replacement parts and upgrades. It was time for new bulbs so I decided to start over with T5s, I started searching ebay and craigslist for lighting, sump and a stand (the old one doesn't look so strong after we had a few inches of water during Hurricane Irene). One thing leads to another and now I'm building a 90 gal to replace the 55 (and have more than doubled the original budget).
