just wanted to start a thread about my 4 (technically a 3.7) gallon invert frag tank I'm starting! I've never done a tank this small but it'll be a fun project. The tank I'm using has a back 3 part chamber to work with for filtration and came with an led light that has day and night options but I'll probably still upgrade it before I get any frags. Right now I just have the sand and the dry rock in there, will update as I go
