Mag drive pump owners...

[nasotang00]

I was looking into getting a Mag18 for a return pump. I just read that they are "not recommended for saltwater aquarium external use"
That is the first I have ever heard of this.. Why do they say that they can be used internally and externally. I cannot find their homepage to look up this information. Is anyone useing these externally on their system>
Thanks

Im using a mag 9.5 externally for 4 months now with no problems. Never heard of them not being reccomended for that?

I have been using a Mag 7 as the return pump from my fuge (running 24/7) for a year and it is still going strong!. I also had a Mag 5 on a skimmer and still have a Mag 2 on my calcium reactor. IMO, one of the better pumps out there (for saltwater as well).

I have heard that magdrives can be problematic when used "externally"...they may develope leaks and they tend to make more noise than other external pumps. But I've been running a mag12 for a long time submerged and I've never had a problem...matter of fact I intend to get a mag18 in the near future but it'll also be used submerged.

a Mag18 might cause hurricane conditions in your 55. I started with a Mag9.5 in my 120 but just upgraded to a Mag12-perfect. Great pumps.

I use a mag 24 (submersed) with 15 foot of head. It works great, lots of power and have not touched it in 9 months. Speaking of which, I should probably break it down this weekend and clean it out......
only complaint, its loud. Small price to pay for dependability!

I'm using a Mag 18 on my 400 gallon reef, externally. It does make alot of noise, but it has not given me any problems. I also run a Mag 12 on my ETS, that I've had for 7years and still no problems. Best pumps I've ever had.

Thanks for the replys. also, this will NOT be going on/in my 55 gallon. I am looking for it to go on my 125 when i get it fully set up. i seems that i may be using it internally.
Is it still real loud internally?

depending on how fast your going to purchase I will give you some feed back on the Velocity T4. I am going to order it this week and set up a closed loop system outside the tank. I'm told it is much quieter than the mag's. But don't know first hand yet.

Another mag 24 user here
I have it external and it is louder than it should be.
Sounds like a small server room under my tank.
Not super loud, but enough to notice.
I keep thinking of replaceing it, but it's ran almost 2 years now with no problems at all.
Also, comparable pumps with same output as mag 24 seem overpriced, but maybe you get what you pay for?

hey kipass, is there any truth to your avatar? Do you study the arts?

I used a mag 7 on my 45 for 3 years - no problems still works. Recently upgraded to a Mag 18 on my 55 - great amount of flow.. no hurricanes. The only problem I had with my mag 7 was when I let it go dry, and it damaged itself - but it still works - amazing pumps!
