I recently was given older 29 gallon Oceanic Biocube with missing parts and balast that did not work. Spent 1 month cleaning and figuring this thing out. Bought a new light and took the top completely off. Found out most of parts from coralife biocube won't work on oceanic. I ended up modifying the filters and adding a light. Finally got it up and running and cycled and looks great. I've got 1 dwarf gourami, 6 small tiger barbs and 3 small zebra loaches. After getting the forst set up I really wanted a small tank in my bedroom so I found a jbj 10 gallon rimless on sale and picked it up. Did some aquscaping with some rocks from my larger tank and some cycled ceramic rings and through in some Fritz Turbo start and added 2 black skirt tetras from my larger tank. Water is perfect and really enjoying the hobby. Let me know what you think.
