The original Remora Hang-On has been introduced in 1999, and since that time it has become one of the best-selling skimmers in the world. The Remora skimmers are designed to hang on the back of your aquarium, taking up as little space as possible.

Patented needle-wheel system with aspirating Venturi creates micro-bubbles to vigorously remove dissolved proteins. Unparalleled water/air mixture means greater foam production, and angled dual injection outlets increase contact time within reaction chamber. Adjustable water-level dial stabilizes water flow for outstanding control over foam consistency. Features bubble diffuser to prevent bubbles from flowing into your aquarium and an easy-twist collection cup with drain line (Models 125 & 220) for quick and effortless cleaning. High grade acrylic construction. Includes everything for convenient hang-on or in-sump setup.

With a height of 6.5″ and 2″ in diameter, the Current USA Fission Nano Skimmer has been design for the nano aquarium. It is powered by a powerhead pump (84 gallons/hour) and should be easy to install and is recommended for aquarium up to 12 gallons.

Two years ago I bought a Weipro Skimmer SA-2017 for an 80 gallon FOWLR tank. After buying 120 lbs of live rock at $10/pound and a brand new tank, my budget was a quite low so I decided to save a little by choosing a Weipro skimmer. They are the cheapest skimmers I know.

The SeaClone protein skimmer can function as either an external hang-on or internal sump skimmer and comes complete with a Maxi-Jet pump. The tornado-like motion inside the SeaClone protein skimmer removes organic wastes from your aquarium. The SeaClone protein skimmer requires no air stones and is more efficient than air-driven protein skimmers.
