Welcome I also switched from freshwater angels to reef tank.. now working on setting up my 30 gallon, because the 2.5 gallon I started with is to small now and the 10 gallon I have going now is to small, but works for starting up frags to move to the 30 when I have it all set up. So I figure in about a year the 30 will be to small...LOL very additive this hobby
