Not only do my cichlids love riding the waves, but it really keeps my aquarium floor and decorations cleaner. So easy to install and so quiet I have to look and see if the water is circulating because it has zero noise.

On March 4, 2012:
Nice pumps for the money - good spread on the flow of the water being circulated - the 1050 doesn't push as much flow as I thought it would have for 1050 gph - power cords definitely need to be a longer - they look good in the tank - pretty easy to position and hide behind rocks in a reef tank - definitely recommend them if you want good circulation pumps without digging too deep into your wallet....

Didn't have the money for Tunzes or EcoTech's, and these were the next best option. Still bigger then I would like them to be, but they are small enough to be acceptable. My two complaints are that the magnets struggle with 1/2 glass. It is not a firm grip at all, so they can twist on their own. Second is that the power cords are short for larger tanks. They need to be two to three feet longer. They are quiet. I have no idea if they actually put out the gph they claim, but the flow is good. But when I have some extra money I will definitely move to the EcoTech, even if they are really overpriced.

Man, I could not be happier with these! Plug and play right out of the box! Hooked em up to my wavemaker and they're working like a champ! Couldn't be happier with the powerheads or with Pet Mountain.

These have great flow, easy to dust, easier to clean if needed. I've got 2 in my tank and bought one for my nephew, and I'd buy another koralia if needed. Works perfect.

I have been doing a lot of research on this PH and been shopping around. Pet mountain was the only place to get it new and still have the best price. They were easy to work with and even with free shipping it got to my house in 4 days. Can't beat it.

I have seven of the Hydor Koralia pumps divided between three reef tanks , two 55 gallons and one 30 gallon tank, all hooked up to wave makers. The flow is strong , smooth, and not overwhelming to the corals. The magnetic attachment allows secure placement anywhere in the tank along with excellent directional control. I had problems with an impeller assembly on an earlier model and the Hydor customer service was more than helpful. I just bought two more as a gift to my son who is starting his own tank.

We found just what we were looking for and got it at a great price. The product worked just as described and expected and worked perfectly in our 30 gallon tank. It's a great power head and looks great to boast.

On March 4, 2011:
These power heads are quiet and powerful. Placed them on opposite sides of a 49 gallon bow-front reef tank. Set them on timers to alternate on/off every 15 minutes to simulate a natural current. Point them slightly upward to create a ripple effect on the top of the tank. Metal halide lighting (22k) pops the coral hues, Koralias glimmer the lighting. Stunningly realistic effect. Size was larger than anticipated. Make room. Priced for those who prefer to drop their coin on corals. Gently cleans live rock, keeps red slime algae at bay.

I ordered these items because I needed water movement in general at the bottom of my aquarium. I also needed water movement to keep all of my live plants clean and free of debris. This seems to do the trick.

On December 22, 2010:
I bought the Hydor Koralia 750 hoping to increase circulation in my planted FW tank. Mission accomplished! The fish love it, and it is completely SILENT. Nice attachment features. My only complaint would be that the head wasn't able to turn as sharply as I wanted it to. TOTALLY worth the small price. Do not hesitate to buy this great little pump.

Perfect item to circulate the water with the wave controller in my 28gal nano. Highly recommend the Koralia pumps in any size.

On November 5, 2010:
AWESOME PRICE, AWESOME WATER FLOW AND AN AWESOME 2 YEAR WARRANTY COMES WITH IT!!! Don't bother with cheaper KNOCK offs on ebay, they only last a year and the shafts break! I know, I have 2 of them! With these prices, there is NO reason to buy generic!! Thanks Pet Mountain!!!

On October 21, 2010:
Koralia makes a great product, the older models had problems with the impeller shaft coming out, these new shaft-less pumps are great!

On October 7, 2010:
Got a Koralia 750 for my 34Gal and it works like a charm. Great product and excellent price.

I installed this in my new reef tank as I was initially setting it up. It is bullet proof, stays exactly where you want it (due to the magnetic adhesion), is exceptionally quiet, and looks nicer than maxi-jets. I also think it consumes less energy than a lot of other powerheads. I would definitely recommend this! I will be buying another one soon myself.

When my Hydor 4 bit the dust, I started looking for another. I was excited to learn that Hydor had introduced the new Evolution line. I ordered two Evo 1400's from Pet Mountain (the best price anywhere). I love them. No trouble starting up and they produce great flow in my 150 gal. reef. Did I say I love them??? Kudos Koralia!

On August 25, 2010:
these pumps are great for circulation, and they are low voltage which keeps the tank temp down.

On August 25, 2010:
This pumps is great, this is actually my 2nd pump. Good flow, low electric usage.

On August 4, 2010:
They work really well keeps my tank crystal clear I love them and will be ordering a few more.

On July 24, 2010:
The Koralia 1400 is a great product. It keeps the water circulating and there is no noise on start up and the new vibration reducing base is great as well. maintenance to the head is easy

On July 10, 2010:
Love this pump. Blows my fish, corals, and inverts out of my tank, J/K. Really nice pump. Another item I'll be ordering one more of coming soon. You should get one too. So what are you waiting for? :-)

On June 28, 2010:
Great product. Its easy to adjust so you can have flow wherever you want. And its really quiet.

Love it, great water movement and gentle gives great performance without turning my sand bed into a cyclone or trying to rip the tissues off the exoskeleton of my corals.

On May 14, 2010:
I bought one of these about a month ago with the uncertainty of a new product. I know that the Koralia line has been good in previous years but I wasn't sure since I had not seen the new "footprint" size. I was pleasantly surprised when I got the 1050 model! I am currently running 1 in a 75 gallon and I plan on purchasing at least 1 more for flow. You can never have too much flow! Great product at a Great PRICE!!!!

The Koralia evo power head is much better than the older style of Koralia pumps. Its a little smaller and easier to do maintenance on.
