Energy-efficient internal protein skimmer for small aquariums
Easy-to-use protein skimmer with hobbyist-friendly features
Magnet-suction cups ease placement in saltwater aquariums
Revolutionary internal protein skimmer boasts outstanding energy-efficient performance. The sleek Hydor Slim Skim Protein Skimmer is designed to increase convenience while keeping energy use down. Easy-to-set-up protein skimmer is powered by a super-efficient 5 watt protein skimmer pump. Multi-venturi impeller generates a flurry of waste-trapping bubbles to effectively remove dissolved organic waste in saltwater aquariums up to 65 gallons.
Hydor Slim Skim Protein Skimmer allows easy and precise regulation of skimmate (foam containing waste) simply by raising or lowering the height of the adjustable collection cup. Air-control valve allows further adjustment. In-tank protein skimmer features a special intake grid that functions as an effective surface skimmer that aids skimmer function and improves aquarium water quality. Magnet-suction cup mounting system ensures secure and convenient placement. For saltwater and marine reef aquariums up to 65 gallons.

The Hydor Slim Skim Protein Skimmer is designed to be positioned inside the aquarium using the supplied "magnet + suction-cup" supports (for glass or acrylic up to 3/4" thick). It is adaptable and is the ideal solution for aquariums that do not have a sump. After assembling the product, please proceed as follows:
Choose where to position the skimmer inside your aquarium. Remember to clean the surface (both inside and outside the aquarium) carefully so the "magnet + suction-cup" supports can stick properly.
Position the skimmer so that the water level is at the mid-height of the Skimmer Grid.
Position the Collection Cup by adjusting the O-ring.
Connect the pump to the electrical supply.
The following instructions on regulating water level and airflow are only indicative for the start up of the skimmer. It will then be up to you to adjust the system to better fit your aquarium.
Important: The skimmer needs to run at least three to seven days before it starts foaming properly and the setting becomes final. It is possible to notice some air bubbles entering the aquarium through the drainage. This is normal and these bubbles will disappear once the skimmer reaches its operating balance.
Collection Cup Regulation
For heavily-stocked aquariums or for dark foam/skimmate, lift the Collection Cup and lower the O-ring gradually.
For aquariums with normal stocking levels or for light foam/skimmate, lower the Collection Cup by lifting the O-ring gradually.
Attention: It is advisable to adjust the Collection Cup in small intervals of 1/8" or 1/4" at a time. For every adjustment, you will need a few hours before verifying if the foam production suits your needs. Repeat this process until you achieve the desired setting without going beyond the indicated "Minimum" and "Maximum" level.
Air flow can be regulated by adjusting the airflow control valve.
Attention: The air tube should always be positioned correctly on the Collection Cup Lid and should never hang over the side of the aquarium.
Attention: Before placing hands in your aquarium, always disconnect all electrical devices immersed in water from electrical outlet.
Regular cleaning and maintenance of the skimmer and the foaming pump will ensure better performance and durability.
Check the Collection Cup and clean it on a regular basis.
Periodically clean the skimmer body with water to remove any trace of algae or calcium residue. Remember to rinse thoroughly to avoid any detergent residue. Attention: Cleaning the skimmer will "reset" the skimmer and it will take a few days for it to return to the desired efficiency.
Regularly clean (or when airflow diminishes) the air intake tube and air control valve since they could be blocked with calcium, salt or dust residue.
Pay special attention to the foaming/supply pump. Correct maintenance will ensure durability of the impeller and less noise. Calcium residue could form between the shaft and the impeller as well as in the impeller chamber. These residues can cause friction, over-heating and premature wear and tear that compromise the correct function of the components. For this reason, the pump and the impeller should be washed in an acid solution such as MagiKlean (#73696).
Protein skimmers actively remove waste products from fish, plants, and invertebrates before it has a chance to break down and compromise water quality. Learn how protein skimmers also help maintain a healthy saltwater aquarium.
Protein skimmers actively remove waste products from fish, plants, and invertebrates before it has a chance to break down and compromise water quality. Use the following chart to help you choose the best protein skimmer for your aquarium.
The best way to maintain water quality in marine aquariums and reduce the need for water changes is to use a protein skimmer. Unlike a mechanical filter, a skimmer removes proteins and other contaminants from the water column. Learn how.
Protein skimmers are available in a variety of styles and types, so there's a skimmer to fit virtually every aquarium system. This article discusses how to set up the Turboflotor 1000 Multi protein skimmer.
