I have a 29 gal bio cube for sale. it's been up for 1 1/2 years. I just got my 150 gal up and my wife wants the counter space back. can't complain because now I have the 150 gal. the bio cube has 30lbs of live rock which is has purple and red coraline algae all over it as well as the back wall. you can't even see any black on the back wall anymore it has so much. it presently has 3 fish and all kinds of corals in it and a bubble tip anemone. I am presently in the process of transferring them all over slowly to the big tank. the sale will not include the corals or fish unless we talk about that separately. It has 2-3 inches of oceans direct sand in it. .5-.7 mm. I have all the options on the bio cube. in fact I have almost 2 of everything so as not to take a long time when doing a water change. I can do a water change once everyt 3-6 months. I have 2 uv lights, 2 fans, 2 circulating return pumps. 2 tunze skimmers, and in tank media baskets, also the in tank refugium chamber. I have the refugium light, heater, digital thermometer. also, a BRS pro media reactor which I run carbon and gfo. I'm thinking like $600 for everything. I even have the optional LED light in the hood, and have made a custom window screen for the top when I have the hood up. it also will come with all the timers for the lights. I just changed all the bulbs, both the blue and white on the hood and also the 2 lights on the refugium light. you can come by and see the thing all set up with fish and corals, before I break it down for you. this is a fully set up system. just add fish and corals. no cycling even. you CAN'T EVEN ADD ANYMORE ACCESSORIES IF YOU WANTED TO. 510 220-2687 pete. richmond, el cerrito area in california
