I'm setting up my first marine aquarium and have a few questions. First a little info about my setup:

120G Glass Aquarium
Pro Clear Aquatic Pro 150 Wet/Dry for filtration
2 x Hydor Koralia 4 for circulation

I've got everything setup, saltwater mixed and tank filled. I am using a Mag 7 as the return pump in the Pro 150, and it seems a bit loud. Any recommendations for quieter operation?

I also have yet to purchase lighting. For this tank, I'm mostly focused on fish, probably predator/aggressive species. What type of lighting should I be looking at?

I'm open to any/all other recommendations.

Thanks,
Zach
