Positioning circulation pumps

[ndz98]

I have two circulation pumps but I only have one in the tank right now. I plan on putting some coral in next week and was wondering would it be too much to have both pumps in there? And what would be the best way to position them. This is how I have the one positioned now. I changed the position of the live rock though. It's more in the center like a pyramid.
