Had three. All of them cracked near electric plug. By Russ K. on 6/5/2015
Russ K. wouldn't recommend this product to a friend
A little over a year ago I purchased three Hydor Evolution 600's. Every 6 months I clean them in vinegar. When cleaning them this time (third time), the sticker started to peel. I decided to remove the sticker altogether so it didn't flake into the tank. After removing the sticker, I found that there is a crack that developed from where the electric wire goes in, going outward. I was concerned and decided I'd replace it. Then I repeated removing the stickers on the other two units and found a crack in the same place. Due to the jaggedness and non-uniform direction, I am certain these are cracks and not a seem. Basically, my overall concern is that all three units cracked in the same place, and all are near the power cord.
I will say that I never got shocked or anything from them, but I don't want to take that risk for myself or my fish.

Very Good Pumps By Lake on 3/19/2015
Lake would recommend this product to a friend
These pumps work really well. I have 2 850s. They run almost dead silent, turn on right away, and can move serious amounts of water. I would recommend these to anyone who doesn't want to spend a lot of money on controllable DC pumps like vortechs, but also wants very good quality from an AC pump.
good pump for the price By Bruce on 2/12/2015
Bruce would recommend this product to a friend
good pump at a low cost. I have 7 of these in all sizes, use some for mixing salt but most just to create current in my tanks. Very little noise and have no had one fail yet. Have some turn on/off a couple times a day. They work good for that but I don't think it's the ideal unit for a wavemaker

I purchased this power head as a replacement for my Seio that crapped out after about 6-7 years. The water displacement is broader and less direct than the Seio in my opinion, which I think is better for the overall current in a reef tank. Great product.
Quiet, affordable circulation pump By b-christopher on 10/5/2014
b-christopher would recommend this product to a friend
I can't speak for use with any wavemakers or timers, but for an always-on circulation pump the combination of power, quietness, affordability and durability are hard to match.
At these prices, they are attractive emergency backups as well.

For the amount of money you pay for this pump. I cant complain that much, but after have two of these pumps running on the hydor wave maker for around 3 or 4 months, the front piece broke out of both and they began running backwards. I contacted their customer service and they were quick to send replacement parts with no hastle.

Quiet when running By David on 4/22/2014
David would recommend this product to a friend
They are quiet, well made pumps. I have 3 of the 1500. I wouldn't want them on a controller though. I turn them off to feed daily and when they first start up its a very audible noise. Setting these up on a timer would be quite annoying. For strong constant flow, you couldn't go wrong.
Two Thumbs Up for Hydor By Jordan on 4/13/2014
Jordan would recommend this product to a friend
Now this review is not really for the two 600gph evolution powerheads themselves that i bought which work great, but it is more for their customer service if anyone has to ever contact them. I ordered two 600gph heads from BRS. When I got the package I opened every item to inspect to make sure that everything was present, intact, and not broken. One of the powerheads' attachment clips for the upper chamber was broken off. It appeared to be a cause of the assembly from Hydor and not shipping. I shot them a quick email to tell them of the issue, and within 24 hours they responded stating they would send a new upper chamber by the end of the week. It arrived just as they stated. So for anyone here who not only cares about how well the product works but also about communication with their customer service, Hydor's was excellent.

This has a nice broad flow, not a stream like some power heads out there. The clicking on start up is not acceptable with a controller, I am going to try a sicce evo 4 as a replacement.

I have 3 of these pumps. They work great for about 5-6 months. Then they start to clog up and the flow is never the same again. They constantly start in reverse. These pumps also can start making noise down the road. I ended up getting a mp40.
Good but loud on start up. By Beagle on 3/21/2014

I like the mount, the flow and the price. But after hooking them up to my Red Sea Wavemaster, I think I'm going to try and unload them and go with something else, maybe a Sicce. I read all kinds of review of people using them on their wave systems and happy. But the clicking at times is almost unbearable.

I bought 2 of these for my 55 mixed reef. Water movement is strong, but gentile enough so not to blow my frags out of the sand. Works great in conjunction with the wave maker. Would defenatly buy Evo's again from BRS.

Do not use on a wave maker. By David on 2/24/2014
David wouldn't recommend this product to a friend
I purchased two of the 1500 gph's for my 90 gallon tank as an upgrade for the wave timer, I had been running two older 800 gph power-heads and wanted more water moment. After installing the new Hydor units it became apparent that you could no longer sit in the same room with the wave timer on. The clicking that the heads made was so loud. After 24 hours of use they came out of the tank. I am currently using one as a stirring pump in my salt water barrel. Pump is good for water movement but do not use on a wavemaker.
Noisy when used with wavemaker By Pegasus on 2/17/2014
Pegasus wouldn't recommend this product to a friend
I bought three 1150's when I was using a NaturalWave pump timer, and they did okay. I bought a Red Sea Wavemaster and another 1150. The constant clicking/clacking from the pumps on startup was driving my wife and I crazy. It was SO annoying! I sold three on ebay, kept one for mixing saltwater, and bought 4 Sicce Voyager 3's. What a difference... I can actually take a nap in the same room now. Yes, the V3's were more expensive, but they are well worth it. Totally silent startup and running make my tank much more enjoyable. However, these pumps are fine if they are constantly running. On a wavemaker... not so much.
Could be better By Could be a great powerhead on 2/17/2014
Could be a great powerhead wouldn't recommend this product to a friend
At first I really liked these powerheads, I have 3 of the 1150's and one 600. I have the flow set up like a wave surge, 40 seconds on 5 second rest oscillating from one end of the tank to the other. All controlled by my Apex.
In the last 6 months I have had to replace 3 of the covers due to the pump starting in reverse and breaking the rubber stopper piece off. Hydor mails them to me for free but this is getting to be a real pain in the butt! I put them in a vinegar water bath every 60 days so calcium build up is NOT the cause of the pumps starting in reverse. Also,only my 1150 model has this issue.
I would hope that Hydor has fixed this problem in the newer models.

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.

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?

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

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.

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.

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.

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 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..

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
