Flow options for a 120G peninsula tank

[gregzz4]

Interfering kiddies aside, a single MP60 will put a lot of flow on one end, basically blasting anything near it, just to create any wave/flow action
2 40s would be a better idea
A wave box may be your best solution if you are concerned about children and hardware
Although, if you can do it, I've seen some nicely built peninsula tanks using a 4-way plumbed around the top
