Reef tank. Update 2017. What is funny is I had moved the tank to Florida in van (crazy experience) buckets batteries, crazy. My wife shot a pic when I set it back up. Look close, see the glue still visible. I am not much into recognition so I never shot pics of it in New Mexico 9 years old, that was something!!!
Water movement, and then more water movement. Lighting and finally watching and more watching. Your tank will tell you what it needs. You will know when whatever you stick in it just thrives. Also let the animals tell you the secret!!
I have a serious opinion about the fish. Have a plan and wait till you are ready and put them in all at once. Hard to watch when a new one is added and the others kill it slowly day after day. My wife would go crazy asking me to get it out.......and you know how that goes, to much damage to what you have built to get one fish.
lps,sps,soft. 2017 update, are you all wondering about the rocks. The base rock are single pieces from the desert that used to be the ocean. Reef rock attached to the the large desert rocks. You want to know where to get them? Study the earth 10k years ago. The one in the center weighed like 60 lbs. Make your own secrets!!
Work a lot.
