quietest air pump

[hairalgae85]

any suggestions for a quiet air pump would be great. helping a buddy of mine, who has an algae scrubber, uses two of those big fusion air pumps.

switched to red sea reefers, the only thing that can be heard is the air pump,

thanks

luft pumps seem to last forever ..
Is this a upflow algae scrubber ?

Luft or Schego.

thanks. it is one of those algae boxes from a company called santa monica. it lays horizontal in the sump, air bubbles in.
