Thanks for the compliments. This tank has been great to scape. I really enjoy it. To top it off its in my new babies nursery. So he will have loads of staring time as he grows up!!!
As far as what makes the blue its an actinic bulb. In line of the reply of the"Halogen" light? Stay away from them. They are not the right color bulbs. They also kick off way to much heat. They would literally cook a tank of this size in hours. I wish it was as simple as to buy one of them, but its just not the case?
The tank is pretty much stock except for adding two more fans to the hood, and a DIY wooden airstone skimmer in my chamber. There is an auto top off in the tank as well. I just feed it every other day and do 2 gallon water changes weekly!
The tank is up since april, but mind you alot of the corals came from my already established tank. They were all just frags from the colonies....
Thanks again and if you have any other questions feel free to ask!!! I will post pics of my larger tank soon enough!
