Opps somehow we neglected to mention this, thanks to Eric for bringing it to our attention. One of the biggest complains in reef aquaira are noises. We all have and heard them, whether it be our skimmer, or lighting fans or yes thats right our pumps. Tunze decided to expand on this idea and create a pump that is supposedly silent. Meet the Tunze Silence pump which come in two flavors: 1073.020 and 1073.040. Up first is the 1073.020 model (Tunze ,could you make the model names any longer?) which pushes water at 634 gph while eating up 30 watts. The next model, which is 1073.040 pushes 792 gph while hogging 42 watts. The lower model (1073.020) should be on retail stores for around $90, while the higher model (1073.040) should hit for $140.
