Steve's Reef Diary - new experience

Steve: is the one of those filters that has the UV in it? Do you plan on leaving it on all the time?
 
the first one is the coral, and the second one we were told is a sponge. There are a few other small things, which we can't get good pics of that, including what looks like it may be more of the coral, but smaller, more sponge, and something that looks like a tiny feather duster.

Can any one ID these pics?

We added hermit crabs and snails last night. The crabs love shrimp pellets. Can anyone tell us the main difference between the FW API master kit and the one for SW?

We are also planning on adding a second coralife light fixture
