new 120g reef

[mraquatics]

hey guys, new to the hobby and to the site just want to say hi to everyone!

so i just purchased a 120g 4x2x2 with a aquatic life 6 bulb t5 light i didnt purchase a sump because i already have 110 fowlr going for about 6 months now. my question is would it be a good idea to run my 120 with my 110, or purchase a separet sump and leave them as two separate tanks. thanx
