It's a 55 tall. I'm getting a 180 gallon tank next Tuesday. I have 80 lbs of rock a very deep live sand bed. It's been running since September 15. I have a blonde naso tang, a bristle tooth tomini tang, dogface puffer, a cardinal fish, and a Koran angel. On Tuesday I am setting up the new tank with a wet dry filter, protein skimmer, and a new lighting fixture. I don't have plans for corals but want to bring out the colors of my fish. Any suggestions ? Also I have 2 koralia 1400s I am going to upgrade for sure any thoughts. Thanks
