I have been running a 28 gallon nano cube with LEDs since may and my corals get to big for my tank so I thought it would be a good idea to start a frag tank. This is what I have so far. A ten gallon, leds with a HOB canister filter, heater and 2 korallia nanos. For those of you who have frag tanks any pointers would come in handy thankyou.
