Great pump

This little pump is one of the best pumps I have had for circulation. It is reliable easy to clean and puts out a reliable stream of water in my !00 gal tank.

Great Product

I must say these are by far some of most popular and widely used aquarium circulation pumps used in this hobby by beginnners, and experienced hobbyists. I've had two koralias for about 4 years now and I never ran into any problems other than the magnetic shaft expanding due to use but Hydors customer service is AMAZING and they replaced them. Again hydor products are simply perfect for any type of experienced hobbyist.

Flow for 60 Gal Cube

This powerhead was very easy to setup and has been very reliable. Provides an even consistent flow within my 60g cube reef tank.

Hydor Koralia Powerhead

I purchased two of these for my 90g SW Tank and they are working great. If you don't need anything fancy like being able to control the speed should you plan on purchasing a Tank Controller later on down the road. Then I highly recommend purchasing these Hydor Koralia

Good flow

Added good flow to my tank for a fraction of what I could have spent. After adding an extra Hydor powerhead to my current set up my zoas opened up more and previous dead spots in the tank were eliminated. Everything in the tank seems to be enjoying the increased flow. I would love to eventually add a nice wave maker, but for now this gets the job done and stays within my budget.

Power pump

This pump is working perfect in my 75 gallon reef. My first pump lasted 10 tens years and was from the same company. My new pump is installed today and running well.

Good enough

These seem a bit on the fragile side. The housing tends to get brittle with age, causing the mesh to crack. They seem quiet enough. Try using star-San brewing cleaner on them. It works really well.
