2+. My 120g DT is a craigslist special. And I built the stand and hood myself.Buy as much as possible 2nd/3rd hand.
Could you elaborate on the light you use please?As a fellow "poor" reefer:
1) I don't go high-end brand names. My aquarium is Marineland, most of my equipment is knock off brands and my lights are black box. Red Sea, etc is too much for me.
2) I go slow. Parts for my system were bought month by month over time. Trades, used stuff and a bit of wheeling and dealing helped.
3) I keep my system simple, so that maintenance is cheap. Filtration is mostly export-based (skimmer and refugium) so that I don't have to buy lots of filter media.
4) I have one reef tank, rather than multiples.
