How many wave makers?

Hi guys, I have a Reefer 525 and currently have one MP 40 on one side of the tank. I have it running at 81% the tank is almost 5 feet wide. if I do have to get another, should I step up to an MO60? I ask only a 60 would need less load I assume and work less. TIA

I think a 60 would be too big I would go with another 40
