With the ice storm we had this weekend, I ended up burning out my main return pump. It was an internal pump, and I am wanting to go with an external pump that will run my display, frag tank, and media reactors. I'm looking for something in the 2500 to 3500 GPH range. I was considering doing either a sequence dart or a mag drive 24 or 36. I'm also looking for suggestions on where is the cheapest place to get it.
