I'm excited ...my new tank stands 6ft 10in. A work in progress, 48" base 90gal tank and 18" cover. This will replace my 30gal long. I will be putting in a 400w.MH. And just how many fish do you suppose I can squeeze in???? =)...... I already have about 40# of live rock, some shrooms, some polups and various other frags I'm growing.
