The AquaC Remora and Remora Pro are undoubtedly the most efficient hang on skimmers available today, and what better than an accessory that boosts their performance by as much as 20%!

The AquaC Surface Prefilter is a special box designed to hide the skimmer pump, thereby creating a more aesthetically pleasing aquarium. The Surface Prefilter isn`t just about looks, however. Ever notice that oily "skin" on the top of your aquarium? The Surface Prefilter skims water off the top of the tank, which is often coated with a heavy load of organics. This can improve skimming by as much as 20% (much darker, smellier foam), and the prefilter has a slotted edge just like an expensive overflow box.

The Surface Prefilter also contains a bubble eliminating sponge to get rid of those microbubbles that sometimes escape back to the aquarium. The water return area can also serve as a media chamber for those who choose to use activated carbon or phosphate removing compounds.


Dimensions (L x W x H): 8.5" x 2.5" x 7.25"

The Surface Prefilter installs in seconds and requires no tools - just attach to the pump and turn your Remora or Remora Pro hang on skimmer into a waste removing machine!

Works well but...

A good product except the suction cups fail after about a year. Would be better with a magnetic option.

good idea, but...

This item isn't really getting it done for me, but I'm not going to slam it because it may meet someone else's needs. Pros: It's always a good idea to skim the surface of the water where the oily film and organics are concentrated. Hides the pump! Cons: If you run a high water level (my tank is a Mr. Aqua 17g), then the box must be moved far enough up that it's locked in position with the skimmer (i.e., the Remora outlet is trapped side-to-side by the outlet side of the box itself). When the Remora and pre-skimmer are so engaged, the intake of the pump is right against the wall dividing inlet from outlet sides. This seriously impedes flow; as I'm looking at it, with all other flow devices turned off, the water is *barely moving* into the pre-skimmer. Teeth on the back but not the side? Seriously? I want to skim the surface, but this doesn't work with my setup. Unfortunately, it looks like I'm now going to need to buy a totally different skimmer.
