reliable pump By TimSc on 10/28/13TimSc would recommend this product to a friendBought it to replace one I had been using for 15 years
Terrible Customer Service By Derik on 9/27/13Derik wouldn't recommend this product to a friendThe pump worked awesome for four months then it would just shut down. If I unplugged it for a couple hours then plugged it back in it would run for about 15 minutes then shut off. I reached into my sump to remove the pump after it had shut down and was surprised that I got a moderate shock once my hand touched the water. When I contacted the manufacturer (Danner) about warranty replacement I got a really snarky response from the rep Christine "FYI it's never a good idea to put your hand in water with a pump plugged in" - while that is true, we are talking about something designed to be submerged in water. I wouldn't buy or recommend another based on my experience.
Powerful pump with little noise By Brian on 9/25/13Brian would recommend this product to a friendThis pump really surprised me. When I purchased this I was really just looking for price. Boy was I surprised when I plugged this in and saw the column of water it created.
I'll admit that you can hear this pump running but it is not annoyingly loud and is definitely a good deal for the price.
LOUD By Dan on 5/11/13Dan wouldn't recommend this product to a friendWay too loud for my setup. Moved plenty of water, but I needed an Eheim. Decided to keep it for water changes.
Perfectly happy with pump By Christian on 3/21/13Christian would recommend this product to a friendI love this pump. It pumps a good amount of GPH to my display tank, and it is pretty quiet. It is slightly noisier than Eheims I bought in the past, but I bought a silencer pad that helped cut back on the noise.
I wish it had a suction cup slide mount!
stand back! By grobro on 3/5/13grobro would recommend this product to a friendThis thing has some nuts! Tried the $25 Eco pump, it was a joke compared to this. The Eco pump did not have the power for my drip irrigation system. But the Mag-Drive dose! Just don't do what I did. I tested it in the kitchen sink, the results was very dramatic, everything within 10' was soaked in two seconds
Rock Solid Pump By Joseph on 3/4/13Joseph would recommend this product to a friendI've had several Mag Drives in the past. Currently I alternate between 2 Mag 7s in my mixed reef for return duty. I went an entire year without cleaning one Mag and it was still going strong. Absolutely zero problems our of these guys. The only minor problem is that they can be noisy, however given their price point more than makes up for a little noise.
A little noisy By brian on 11/30/12brian would recommend this product to a friendHooked this up along with the Mag 5. Both are a little noisy not any louder than an ecotech mp40 on 100% but still noticable. Very reliable and powerful.
Great pump By Reuben on 9/14/12Reuben would recommend this product to a friendI installed this pump on my 40B Reef tank. I must say I am super please with the performance so far and how quite it is running. This is an awesome pump and glad I bought it.
Workhorse By Earl on 9/13/12Earl would recommend this product to a friendThis little guy has been running steady for 1 1/2 years and just keeps on going. Very reliable, and quiet. I run it with the foam prefilter in place and clean it on a regular maintenance schedule.
Great pump By Patrick on 9/10/12Patrick would recommend this product to a friendPumping water from my water storage barrels in my garage into my aquarium with a 6' height difference is no problem. No more carrying buckets. Plug the pump in and let it go. It has a quiet operation and makes water changing faster.
Great pump. By TYRUS on 9/3/12TYRUS would recommend this product to a friendGreat pump, using it with my BR-140 Octopus biopellet reactor.The only downside is that it is noisy.

can i use this pump as an external for a DIY canister filter
Bulk Reef Supply Hey Robert,
Technically the mag drive can be used externally though we generally don't recommend it. The input side of the pump has a very fragile connection that is easy to break. For external applications we generally recommend a pump whose main purpose is to be run externally, like a panworld or Iwaki pump.
Danner Mag-Drive Supreme Pumps are specifically designed for the demands of salt water aquariums. Mag-Drive Supreme pumps are made to run continuously, without seals to wear out. Very low maintenance with an easy-clean pre-filter. These are the most used pumps in their class. Energy efficient. The only moving part on a Mag Drive pump is the ceramic/magnetic impeller. All Mag Drives come with a 3 year limited manufacturer's warranty.
