Hydor is an Italian aquarium hardware manufacturer specializing in advanced water pumps
, and filters
. Since 1984 Hydor has been researching and introducing new technologies into the aquarium hobby. Hydor’ s PTC (Positive Temperature coefficient) heaters make it impossible for a heater to accidentally over-heat the aquarium.
Hydor also pioneered small nano protein skimmers that rival larger designs. Using a synchronous centrifugal pump, Slim Skim protein skimmers
are silent and extremely efficient. Hydor may be best-known for their Koralia line of water circulation pumps. Koralia pumps have been continuously improved and are now compatible with a smart controller.
