Tunze pumps
I've got 2 Tunze 6100s and a nano 6055. All variable speed, which makes a huge difference in the tank (e.g. they slow down at night and are programmable for storms, surge, waves, etc.).
Expensive, but well worth it. One thing not mentionned on this discussion is the fact that their transformer units are outside of the tank, keeping heat exchange down.
You may want a 7095 multicontroller if you've more than one Tunze pump. I've got one if you're interested (see for sale section).
I've been running my pumps for more than a year without a hitch. They can be noisy when they surge to 100 percent, but it's usually vibration and can be corrected by shifting the pump position.
Cheers,
Erik
