low power high efficiency pumps
 

I'm a newbie, so I apologize if that's an old, hashed topic.
I'd like to make a survey for submersed pumps with algae/dirt
'milling' capability.
I'm looking for the sub 1000 Galon per hour range - and power
consumption less than 200 Watts.

and yes, that you have a good experience with its reliability and
longevity.
any information will be appreciated
thanks in advance
