Good utility pump...
| General |
Mag pumps are great utility pumps, they will move a lot of water and can handle a fair amount of head pressure. They will tend to heat up the water they are operating in do to the higher wattage needed to run them, so there are better choices for return pumps. However, Mags are great at moving water from point "a" to point "b" and to use as salt mixing pumps. |

Draws more wattage and runs hotter than some comparable pumps of same flow rate.

Danner Mag Drive 7 pump review
| General |
I used this pump on my 75G with an Oceanic Reef Ready sump 1. The unit did what it was supposed to do for the first couple of years but it started to get very noisy overtime. I cleaned the impeller every few months but the chamber seemed to enlarge anyway. The flow rate dropped considerably with about 4-5 of hose rise (length is common). My set up required me to splt the Barbs to have a dual output on my return and the pump just did not produce and sort of current. I upgraded to a mag9.5 and the difference is night and day. I did not want to add power heads to my display tank and that was part of my choice in upgrading. The 9.5 does not nearly loss as much flow on hose rise compared to the 7. overall it is a solid unit but you need to keep up on the maintenance monthly / bi-monthly or the unit will increase its db range. The pre-filter should be larger because I had to clean mine every 2-3 weeks or it would cause problems with the pump. |
