My reef is still pretty young, however I do have several that I need to frag. I've started with high end stuff with the long term goal of being able to have some really nice frags available at reasonable prices or trade. I've moved several to a friend's reef tank's since her husband with alzhimers really enjoys watching them. I definitely realize that for most people even $50 frags are out of reach and I hope to be able to have some really nice stuff available in the not to distant future.
My current systems are a 65 with a 25 fuge/frag system and a 90 with currently a 30 frag tank/fuge (hoping to upgrade sizes soon). I'm currently keeping mostly lps, a few sps and an assortment of rock and bubble anemones. I run a mixture of radion xr30w gen 4, radion xr15w pro, leds I built and a couple pc's.
