Sorry I took so long to respond. I'm looking for something internal. Is the one that have internal? Also can it be dialed down cause it might be too strong for the overflow, I could be wrong. I'm pretty new to this stuff.

The mag7 looks pretty good and its not as much as other pumps. Thanks for the links. Since its now a 30 gallon should I go with something smaller than a mag 7?
