Just what i expected By Bradb90 on 12/14/2013

Very good product. It is well built, made of high quality materials and I expect it to give me many years of use. I bought two of the 850gph for my 60g and they do the job just fine.
I definitely recommend this product.
Just what I was Looking For By Marc on 12/10/2013

Using the 850GPH as a circulation pump in a 55 gallon. Works as advertised. Seems to be the right size for my tank. Perfectly silent, very easy to mount with suction plus magnets. Exactly what I was looking for and about $25 less than at local aquarium store.

Just take them out of the box and put them to work. Simple and effective. Quiet. Magnet good and strong for mounting.
Love these pumps By Dioncuda on 12/8/2013
Dioncuda would recommend this product to a friend
Well lets see,for the money they are awesome.I just wish they were smaller and put out the same flow. That being said, you forget about the size when you see the flow they put out and everything opens up.
Time for a bigger tank:)

Nice Flow and Silent By Jake Wilkerson on 10/15/2013

Silent operation and gives great flow. I've owned these in the past and as long as you keep them clean they'll give you years of great service.

The hydors work great! They are easy to mount and perform flawlessly. It would be to anyone's benefit to own a hydor koralia pump!
HORRIBLE! By William on 9/29/2013
William wouldn't recommend this product to a friend
They are absolute junk. Yes they work great the first 9 months, but I can almost guarantee that they will start running backwards....if you don't believe me, go on any reef website or Google Koralia running backwards and you will see. You have to send for replacement parts. All 3 of mine have done the same thing and they are 11 months old as of this post. BRS...PLEASE STOP SELLING THESE!!! Better yet, why are you putting your recommendation on them?
Great Powerheads By Brian on 9/25/2013
Brian would recommend this product to a friend
I have two of these, a 600 & 1150 gpm. While I am new to this hobby these powerheads seem to create good flow and are practically silent. I have to practically put my ear to the aquarium to hear these guys running. All around great buy and would definitely recommend.
Evolution 750 By DM on 9/6/2013

I had to mention this for those who are experiencing broken front covers. I was using this powerhead as a wave maker and experienced the same issue with the broken front cover. However, I shot Hydor an email and they sent me 2 replacement covers free of charge. You really cannot go wrong with a company that stands behind its product. That is why I will continue to buy Hydor products and make my purchases from BRS.
Good entry level pump By Bill on 8/12/2013
Bill would recommend this product to a friend
As long as you aren't looking for a wavemaker feature, this is a good inexpensive pump. However after running these in wavemaker mode on my reefkeeper, they soon began starting in reverse or just not starting at all. As long as you plan on running them constant they seem decent. I've since bumped to the way over priced Vortecs and I LOVE the upgrade.
Only powerheads I will ever own By William on 7/23/2013
William would recommend this product to a friend
I use one 1500 GPH and four 600 GPH powerheads in my 110gal saltwater fish/rock only tank. They create the exact water movement i want. I use the 1500 behind the rocks to keep from creating any dead spots and the 600's (two on the back and one on each side) to create the perfect flow to reduce nuisance algae growth and keep a health flow for the fish.
Very good product, better prize By Sakura2282 on 6/22/2013
Sakura2282 would recommend this product to a friend
I bought the 1150 GPH for my 46g bow front tank, but I'm not sure if it's the one I need for it because I just started in the reef hobby, but this pumps does the job. I can see how it moves the water inside the tank.
Right now I'm using it to help me cure the pukani rock I bougt brom BRS, but I will probably buy another one less powerful than the one I have now, just in case I need more water movement in the tank.
Not as great as the reviews By Michael on 6/6/2013
Michael would recommend this product to a friend
This is a very quiet powerhead. I purchased the 600GPH, however it easily feels like its blowing 1/3rd the power of my Marineland 700GPH powerhead. Now I wish I got the 850!
I'll likely be replacing this at some point. 40g Breeder reef tank.
HYDOR KORALIA EVOLUTION By jeromi on 6/5/2013

I got two of these pumps (the 550gph) for a 55 gallon tank. Worked great in that small of a tank. Unfortunately due to me being an idiot I cracked the tank and had to upgrade (OH DARN.. Right?!?!) now that I have the 120g these things are way underpowered. I like them though and will probably get two stronger pumps.

Good By Kenneth on 5/10/2013
Kenneth would recommend this product to a friend
Product does work, however I had two of these in my tank and not quite sure what happened but the plastic piece in front of the blade came apart on both pumps after about 4 months of operation. I purchased two more and they are running fine. They keep everything suspended and provide good movement in the tank.

Have used product for years, does a great job of moving water in my 135 and 95 gallon tanks. BRS pricing is great and selection of products offered is great.
Not enough power/flow for a betta fish cup By Jeff on 5/3/2013
Jeff wouldn't recommend this product to a friend
I purchased two of these so I can use the wave maker setting on my new reef keeper lite as it was a recommendation from BRS and I couldn't be more unhappy with them. They click to loud for my liking so I can only imagine the fish inside and they just don't have any flow to them. Sure if you stick your hand on the cage in front of them you can feel it but a few inches away they have nothing that you feel. I have them in a 29 gallon tank so I am sure that the recommendation came from simple mathematics but I am using them and one is sitting in a box as I grabbed an old one I had until I can buy new ones.
Please don't see this as a stab at BRS. They are the greatest people, great products and timely delivery. I have since purchased from them and continue to do so. Hydor has over rated their product

this is the quietest circulation pump I've ever had it is near silent and I mean near silent.

Everytime mine turns on it makes a bad grinding noise. It's done it since the first time it came on, I thought that was the point of the evolution line. I do have a 750 thats quit though.
Great pumps for the Money By Brandon on 4/8/2013

You can't beat these pumps for the money. I would like to have to Eco Techs but I just can't part with the cash yet. One day I will then use these in another tank or in my RO/DI reservoir. Work great for now the fish love the current they create and they are whisper quite
Great Pump! By Chris on 3/26/2013
Chris would recommend this product to a friend
Far superior to the maxi-jets I had in their before. Bought the 740 evo's for my 55g. Near silent, magnet mounts are incredibly better than suction cups and the indirect flow is nice. This will be the only pump I use from now on
