Well, I have decided it is time to buy a new tank. My dilemma is as follows: I met a guy who is selling a 20-year-old 55-gallon tank with rather thick glass (no cross beam in middle of tank). It comes with a heater, biofilter with power jet (no mechanical filter), a single 48” light, and a somewhat broken glass top. All for $100. I was also at the local fish store where they have a 55 gal setup (new design with middle cross beam and thinner glass), an attached filter, hood with 2 x 24” bulbs, and an assortment of other stuff for about $160. I am also debating about just buying an aquarium, hood, and adding a filter, heater, etc to my setup. Anyone comment if it is worth it to buy a self-inclusive kit or should I piece it together? What about the older tank? Any comments appreciated!
