So, I recently acquired a 14 gal Oceanic nano. It was all original down to the bioballs. So far, I changed the substrate to Aragonite sand, added live rock from my main tank, and some corals. I also added a Korillia wave maker for flow. I have heard that, I should take out the bioballs (I agree) and install a media rack in that chamber. The lights are still Power Compaq, so they need a upgrade. I would like to add a skimmer, but this seems to be a challenge. Maybe down the road I could add a small custom built sump, but not now. I would love to hear some ideas/suggestions from all those willing to help out. One more comment, I would like to keep the original top on the tank. Thanks' in advance, Dennis
