My tank is looking gorgeous, thanks to a bit of help from ya'll.
sorry for some of the stupid questions!!! ha!!!

But now the idea of (do i or don't i need/want a refugium set up)

I've got a great skimmer, hang on back filter, lots of great live rock, etc. on crushed coral instead of sand(algae issues)........

Cheto growing at the bottom right of tank seems to help w/ any algae issues... but I may just have idle hands and want more, more, more stuff.

Any ideas from you saltbrains out there???
