I am in search of a quiet inline/external pump.
I am using a 90 Gallon Reef ready going into a CPR1000 Wet Dry. I have a 3/4 bulkhead coming out of the sump side that the pump can go into. I am going back to the tank with a UV
Right now I have a Mag 7 in the sump submerged and I have also tried it externally inline and it is noisy. (motor sounds, not air sounds).
I was looking at something like Iwaki, but I have heard they aren't that quiet either.
