Hydor Koralia Magnum Aquarium Circulation Pump, 1650, 2250, 2750, 3250 GPH

Hydor Hydor USA First Impressions

Nicely made.

It drives a 5ft fluidized bed filter and CO2 reactor tower. It works, it's not too expensive, and I'm happy. The bubbles are noisier than an air-stone. I've had it running for almost a week, and it's basically silent. Arrived well packaged, brand new in original box, fast delivery via Amazon Prime. I have not found the replacement bulbs available yet. Third pic was taken 15 days after the first pic, 5 days after the second.
