Hydor Continues to Perfect Their Market Niche.

Hydor. If you havn't heard of them, either you live under a rock, or you've never seen the need to replace your Tunze Streams. Hydor is a well known aquarium product maunufacturer from Italy, though when most reefers think of them, they think of the egg shaped Koralia powerheads with magnet attachments, and with good reason.

The Hydor Koralia is another take on the popular Propeller-style pump, like the Vortech or Tunze streams, which deliver powerful yet broad water flow with little head pressure. This makes them very ideal for Reef tanks requiring massive turbulent water flow. Normal output pumps produce more of a thin column or jet of fast moving water that is not very efficient at creating the random flow needed for a reef tank. The flow normal pumps produce is a constant laminar flow, which is completely unnatural for most corals and can actually cause certain corals, like Euphyllia , to recede from their skeletons if placed in direct flow.

Anyway, propeller-style pumps have revolutionized the aquarium industry, and it's nice to see the innovations havn't stopped. A Hydor Sales rep came in to let me know what's been going on with the company. Besides their Aerio pumps being in CPR's new line of protein skimmers, Hydor will be coming out with their own Nano Skimmer, the "Slim Skim" designed to fit most "Nano" systems. They have also announced the release of the "Marine Performer" skimmer for larger systems.



They also will be advancing their next generation of powerheads by introducing "shaftless" impeller designs. This is said to cut out the rattle on start up of these pumps, with the benefit of being able to connect the baseline Koralia to wavemaking devices. The former pumps would fail to start, rattle, or worse, reverse flow when connected to a wave timer, causing your pump to become a fish blender unless fitted with the protective screen.

Hydor as already released a line of Controllable Koralias to be used with their dual or quad controller. Performance is very good with intuitive conrtols, however it may not have been the correct market to introduce a rather expensive controller. The world of higher-end reef equipment is highly competetive and companies like Tunze and Ecotech have carved strong market shares out with their respective products, and there must be innovation to compete.

Koralia powerheads are about as good as any other prop pump, but their incompatibility with other controllers has kept many reefers from incorporating them into their systems. Hydor has proven they can adapt with the times. Their powerheads have proven to be a best buy for water movement.

I was also given one of their blue LED spotlights, its similar to a moonlight, but also available in red or green. The spotlight produces some very dramatic effects in the corals.
