Upgrading my bow front 75 Gallon and looking to go with a bigger tank! 3 choices i have narrowed it down to are 155 bow front, 140 tall and 140 regular, all of which are reef ready. Cant decide between the 3 and would welcome any and all suggestions on which to go with. Its a softie and acro tank with small fish and I'm going to use a deep sand bed probably 4" with HQI lights. Also any suggestions on places to find good deals on tanks this size are welcome as well as any tips on what type of equipment i should use with it as far as skimmers and what not.
