Just wanted to say hello, been reefing for 6yrs. I am currently building a 125 that is currently cycling. My 20 gallon has been up and running for about a 1 1/2, I started it to just to scratch my reef itch. After having a started with a 30, then a 46 and then a 65. I got out for a couple years, but i would still go to the LFS. I can't shake it, maybe they have classes for us reef junkies.
