I have 2 of these in my 46g - they move the water very well...my corals do very...and there are no dead zones in the tank.
One of the Best By JP on 2/8/2012

I purchased the 750 for a 40 gallon reef tank. It has been running in my system for over a year now with no issues what so ever. It runs extremely quiet and it very easy to clean.
I would recommend this item to anyone looking for an inexpensive extremely reliable powerhead.

This power head is really quiet and provides the circulation I wanted. I use this powerhead in my 55 gallon saltwater mixing tank and it does a great job.
Great value, and controllable... By Allan on 1/25/2012

Just got a trio of 1400s for my 75 gallon, and I'm very pleased with the resulting flow. These replace a Koralia 4 and two Koralia 2s that I've had for a few years. They worked ok, but I wanted to put them on a controller and when you do, they clatter like crazy.
The new evolutions do not clatter but about half the time they do make a sort of thudding sound on starting. The thudding sound is not a big deal to me. MUCH quieter than the original Koralias clattering.
To those complaining about these starting in reverse: The prop needs to be able to move forward in the event that it starts in the wrong direction. The forward movement causes it to hit a rubber bumper (cause of the thudding sound) which stops it and gives it a chance to spin the other way. If the pump is dirty then the prop may be prevented from moving forward, thus there is nothing to stop it and get it going in the other direction. If you're having issues, then give it a good cleaning, and maybe a soak in vinegar.

I got one of these 750 power heads and it is a great value. Very easy to take apart and clean and works like a charm. Very low power consumption which is a plus.
good flow By Andrew on 1/6/2012

They are clean and quiet and move a great deal of water more diversly than my previous power head a maxi-jet 1200. The pivot ball construction allow for wide array of positions. Evo pumps are good and I am very pleased with the purchase , I look forward to using them in conjucntion with the smartwave wavemaker, my only concern, or would like to see explored is the design to move the power cord outside the tank like the vortech, the magnetic mount is great, but would have an even cleaner look if they could evolve the technology to an external wire configuration. It a great balance of flow enough to move the water but not too much to blow softies around

For the price its a good little pump that works best if it is run continuously. Shutting off for feeding times or water changes can be frustrating due to the pump often going into reverse. Shut it off and then back on and sometimes it corrects itself.

I used two of these side-by-side with a magnum 5 and an older Koralia 4. Produces more flow then the 4, and nearly a much as the 5, but is smaller then either of those. Quiet, and controllable with a wavemaker. Excellent pump and a fair price.
Hydor Koralia Evolution 1400 By pk on 11/20/2011

This would be a great pump if the magnet shaft didn't split and swell up so much that it wouldn't turn anymore. This pump starts up sometimes, sometimes it doesn't and sometimes it starts in reverse. Outside of these things, it great!
great, but large By Mario on 11/17/2011
Mario would recommend this product to a friend
After seeing many tanks with vortechs and tunze, this powerhead is relatively large, but it is perhaps the quietest pump i have owned. It also gives very good, wide flow, but if only Hydor is able to make it smaller somehow, it would be amazing. It also does not work well on a wave maker, as there is an annoying clicking sound.

I am using these on my 40g long frag tanks which are 48" long and they move the water nicely. As always the magnet holds perfect and they seem industructable for 7 months and counting. Very easy to take apart and clean. For frag tank flow or basic flow for any reef that you do not need control these are great powerheads. Overall a great value for ther money.
