I personally like the mag pumps .I run it outside the sump .I have a "quiet one" that I bought to replace the mag but its noisy outside the sump.Inside the sump they both run quiet but outside the mag is quiet and the "quiet one" is not
Yes I have heard about the eheims but I heard there are cheaper alternatives. I have read a lot of people are using the oceanrunners and seem to like them a lot.
Basically I have a 135 gallon with the sump in the cabinet underneath. The output of the return pump would basically be split into two return lines. So THere wouldnt be a lot of resistance to flow. i was thinking to get a 1200 to 1600gph pump?
I have an ehiem 1260 which i bought to replace a Mag7, whic i bought to replace an Ocean Runner3500. The ehiem is by far the quietest pump I have had, and the mag7 i would rate as a fairly noisy pump. The 3500 was not bad but no where near the ehiem.
In my opinion the ehiem is worth the extra $20 or $30
