I got the tank over the past weekend and almost all livestock made the trip. I am still cleaning and setting everything up. I changed the crushed coral to argonite sand. I added another powerhead to this system as well as replacing the small rio powerhead that came with it with a 1200 with a orbit attachment, just like the other powerhead that came with the tank. I also through out this guys protein skimmer, it was a piece and not working. I had bought the coralife super skimmer 65 back when I was going to do the 29 gallon, so that is on there now. I am also in the process of cleaning out a included hang on the back refugium that he gave to me to. I plan on getting that on the tank, right away. I have two questions. First off the lights are definately not enough. Should I keep the current setup and just add some medal halide. The current lights are 2) 65 watt 50/50 power compacts, and 2)65 watt actinics power compact. So basically a total of 260 watts. Definately not enough on a 72 gallon. What are everybody's suggestion on lights? My thought was to keep the current setup and add on some medal halide, but before I do I wanted to ask everybodys opinion. Second question, what type of algae do I buy to stick in that hang on the back refugium, to help get rid of toxins in the tank? Any and all help is appreciated.
