I have a Nano (fish, hermits, and shrimp) that I have had for close to a year in an Eclipse 6. You just cannot get enough light in it for any corals. So yesterday I bought a Bio Cube 14 so that I can finally have a nano reef (wanted the 29, but just do not have the room for where I want to put it). I also bought 15 lbs of live rock, a Fission Nano Skimmer and a Mini-Jet 606 (for more flow). The Nano Skimmer is not going to fit in the back so I will either return it or just run the skimmer over night once or twice a week in the front “feed†door. I set-up the cube with the live rock, turned everything on and watched the temperature climb to over 83. Today, I ran the lights but not the Mini-Jet 606 thinking that this might keep the temp down. It was better only 81.6, but I really think that 10X is on the low side of flow. Tonight I decided to do a mod to try to improve the situation. I removed the top the opened up the light unit. I flipped the fan that pushed air into the light kit over so that it would force air out of the top. Then I cut 3-1 inch long square holes with into the front of the clear light splash cover. Air now flows from the front of the tank over the lights and out both fan vents. The temp has dropped 1/2 a degree in 15 minutes. Will update and let you know final results.
