over kill for a 10g. they will grow SPS in a 30 cube or 2 in a 55.
used current has the best controller and pretty blue glow. marine land but the controller is Meh, they may have improved it.
A used t5 2 3 or 4 tube but heat. A single power compact cuz no boby wants them since t5 came out.
So best cheap coolest timer ramp sweet blue glow, current orbit marine.
if you find a JBJ unibody on ebay get it. no timer no ramp. lil overkill but controllable.
