Hydor has lost its reputation
Pros: Reliable magnet mount
Cons: Inoperable unit securely mounted to the glass
I've had two Evolution 850s for less than a year. Both have suffered from broken face covers, which makes them run backward. Clearly a design flaw based on similar problems mentioned on many discussion boards. Can't find aftermarket replacement parts in stock anywhere. Unable to contact the manufacturer for support. After using their products for 15 years, I'm abandoning Hydor for good.

Great pump for the price
I just replaced this pump in kind after failing from 15 years of use. Must say for the price 15 years is not a bad pay out. That pump didn’t owe me a thing.

Great pump for the price!
Pros: Cheap, reliable, great flow
Cons: 50/50 chance of starting in the opposite direction when using a controller
This is a great pump for water movement, I’ve used several these and love them. Easy to clean. My only problem is that since it’s an AC pump, there’s a 50/50 of the pump starting in the opposite direction when using a controller that turns it on/off and it makes a noticeable clicking noise when it does turn on the opposite direction.

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.

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
