			 Usually the neg feedback on Mags is just the noise.  Like someone else said on the forum here, they are very reliable.  I previously tried Sedra's and I had three in a row seize within their first two weeks of operation.  I gave up on them completely.

 They are good pumps but I find they produce more heat and are noisier than the Eheim. On the flip side they are considerably cheaper though.

			 Had a quiet one and couldn't get rid of it fast enough as it was nothing but trouble and loud. Picked up an ehiem and could not be happier

			 So I see lots of suggestions on pumps but what flow should his pump be putting out for his tank. How many gph should it be rated for? I would like to know this as well, how do you determine what gph have to be moved in the tank?
