Opinions on Mag Drives

[ReefRockerLive]

Who ever uses the Mag Drive Pumps and either likes them or don't like them?

I am running a Mag 9 pump internally for my return and this darn thing is LOUD. I have tried to muffle the sound a bit by adding some prefilter under the pump, but that did not work very well.

What are your opinions and methods for silencing these pumps?

Thanks

I have used them in the past. The biggest concern with them is the lesser quality stainless screws they use to hold the housing together. If you run them internally, I would look into replacing them with nylon. There is a thread floating around here or RC that gives sizes etc.

not so in love with 'em for my tank.

Got one in my front fountain--works great there.

Some are loud. Some are not. They are inefficient, and will heat up the water. They have some poor manufacturing standards also. They use a cheap plastic on the inpellor housing that is suseptable to breaking. I had a loud one that I replaced the impellor on. It was still loud; so I replaced the impellor cover. It was still loud, so now it mixes & heats saltwater.
