Wow, definitely feeling welcome!
What's Hooked? An LFS? Haven't heard of it.
Some answers to the questions - the 120 is 4' long and has the nice amount of depth. Currently have a Vertex Alpha Royal Exclusive skimmer, AI Sol blues LEDs (4 of them), integrated sump in the stand, and a little giant return powering the system. The tank is mostly LPS/softie dominated with some brain corals, leathers, acans, and a frogspawn. Fish include a purple tang, multicolor angel, color beauty angel, a blue spotted jawfish, and a true perc pair that host about 4-5 RBTAs (won't stop splitting!)
The nanocube on the other hand is SPS dominated with frags picked up from Bart (thanks again!) and some nearby LFS - those include a red plasma acro, purple haze montipora, true montipora undata, cali tort, birds nest, rainbow montipora, green spongades, and a tricolor, green candy-cane, as well as an RBTA from my 120. The hood of the nano has been retro fitted with one of steve's LED packages on a dimmable controller. A eheim jaeger on a finnex max 300 heater controller keeps everything warm. Looking to possibily buying an In-Tank media basket, as well as an vortech mp10 - the koralia isn't doing it for me.. Fish just include a occy/buckshot pair of clowns
