newbie

I am brand new to the hobby and forum. I have experienced the fun and joy of freshwater but this is my first Reef Tank. I am curious to know what kind of coral this is growing on the seeder rock. It seems to be doing well and had begun to show in the last few days. This tank is about 2.5 weeks...

i would like to set up a native northeast saltwater tank.. I'd like small local fish as well as crabs and sand and mud....... I'm in info collection mode... I'd like a 75-90 gallon tank..... I'm looking into required filtration..... I'm worried about flooding my basement, so what type of filter...
