I'm fairly new to keeping fish and I was wanting to "step up" and set up a salt water 40g (with a breeder tank). I already have a 20g Long for the sump and have an octopus skimmer. My buddy is going to help me build a stand and set up the plumbing. My questions are, which power heads and what lights would be good for my set up. I am in college and on a budget, but I enjoy keeping fish so I was wondering if anyone could direct me to good deals for power heads and lights.
