Not as great as the reviews By Michael on 6/6/2013

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.

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.

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

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
