Hi every one. I'm Curtis, 47 yrs.young..haha I've had a saltwater tank for about five years now. I'm basically joining with your club, hoping that I will always be able to get some good advice about the different situations I come across. Right now, I have a 75 gal. saltwater tank with 2 metal halides, 2x 175 watts , i believe there 14000 k. In the tank, I have roughly 15 different types of coral.
