I am in the process of getting back into the hobby and will be setting up multiple tanks all using hamburg mattenfilters and/or breeder sponge filters and I am hoping I can get suggestion of pumps. I have never used anything other then dinky pump when I was a kid on a single tank.

Specifically I will have 2 small fish racks. 1x20 long and 3x10 gallons underneath as well as 1x40 breeder with 3x15 gallons underneath.

A few things I am looking for are the ability to service myself and easily find parts, somewhat quiet but does not have to be silent, enough to power all of those tanks with some headroom for more if I decide so. Also don't want one that is completely overkill.

Thanks a bunch.
