Good pump, but... By Brent on 8/13/2014
Brent would recommend this product to a friend
I guess I should have known that using this pump externally might not be ideal. I tried setting this pump externally up as recirc on a saltwater water change tank and it leaked. So, when I went to tighten up the four accessible screws, the casing cracked and I ended up with a bigger leak... grrr... lesson learned. Other than that, I have owned many mag-dorve pumps over the years and have found them to be very reliable.
works great for water changes By Anna on 7/21/2014

I bought this pump for water changes, since good old "bucket method" does not work very well with brand new hard wood floors. Pumps saltwater back into my tank quickly and with no problems. I use it for 30 minutes every two weeks, so the noise is not an issue. If you are looking for a return pump, go with Sicce Syncra, it is very quiet and efficient.

Just as great as it is LOUD. By John on 11/12/2013

This is a GENERAL purpose UTILITY pump. Think "industrial". If you're looking for a whisper quiet pump (heck, even just a quiet pump), look elsewhere. But, If you need a powerhouse of a pump in a location where noise isn't a factor, buy one of these right now. Since this pump does exactly what it advertises, I almost gave it 5-stars, but since most of us prefer/need quiet pumps, I opted to dock it a star.
Too noisy and rattles By SkipperGoby on 7/19/2013

I am setting up a 34g reef tank (my third reef tank). This pump is too noisy. Even just suspended in the water without touching any surfaces it rattles and buzzes loudly.

I have ran the pump in its work just fine. For transporting water from point A to B it work just fine. I got it to pump water 30 to 35 feet away. Money well spent.
Try Something Else By BkTriniBoy on 5/10/2013

Not sure if I just happen to be the lucky winner but the pump I got brand spanking new was clicking loudly and humming like a mens choir. I contacted Danner and they are shipppng me a new impeller to see if that could be the issue. I will admit that their customer service was pretty decent. I however would not purchase another pump from them. Eheim or Sicce seems to be the better options out there. Pay the extra money and get the piece of mind that you are searching for.
Reliable / Noisy By Ryan on 3/8/2013
Ryan wouldn't recommend this product to a friend
Okay pump, I have it for my 55 Gallon tank with 10 Gallon sump, It is a bit noisy, I have used silicone to attach it to the tank, and also placed blue filter foam around it and cannot get it to quiet down. also produces a good amount of heat, it keeps my tank at about 6 degrees hotter than the air in my house. 76 currently. Other than that, it pushes water great and seems reliable I have not given it the test of time. the box says it is warrantied for 5 years.

I've had a Mag 7 going strong for the past 7 years. I haven't replaced the impeller or even cleaned it. These things are tanks!

Loud By DKujo on 6/12/2012
DKujo wouldn't recommend this product to a friend
Contrary to the other reviews, I was very unhappy with this pump. There is a terribly loud humming noise, almost as if there is a rock in the unit, bouncing around. Please do your interenet research before buying this product. These pumps are boasted for being reliable, but do your research and you will see that I am not the only one with noise problems with this pump. Guess I have a new pump to mix water now.
3 years and still going By Manny on 6/6/2012
Manny would recommend this product to a friend
These pumps just don't wear out. I had a problem with flow in my old tank and thought I needed a new pump. When I took it apart after 3 years of no maintenance, the inside was still looking great and working like new. The problem wasn't in this pump, it was someplace else.
They are like the old Timex commercials...takes a lick and keeps on ticking!

These Pumps are the Best By David on 3/18/2012

Other than Ehiem (which are bigger $), I dont know of another pump I would rely on more than these. The 5 is the perfect size to drive bio-pellets in the TLF 150 reactor. Forget about the Maxi Jet 1200. Its not even close. These are great pumps.
good pump By maxx on 2/12/2012

I use this as my return pump for a 20 gallon tank, it is connected to 1/2 inch pvc pipe and a ball valve that regulates the flow. Don't worry about the pump it can take the pressure, it's been running for quite a while now.

I have had Mag Drives for many years and they are always reliable and easy to maintain. Would definitely recommend that you don't skimp on your pumps as the extra money spent now will save you money in the future when you need to replace inferior products.

Great flow By Shane on 4/22/2011

I am using 2 of these to feed a carbon and gfo reactor. These pumps provide plenty of flow even though they are pushing water through over 10 feet of tubing.
