So far in my aquarium life I have only ever used cheap pumps from local fish stores. Has anyone ever used one or the other of these pumps and can give some ideas or comparisons??? It will be used to fluidize Kaldnes K1 media in a sump and also have a split off for an air stone in the tank. What I am most curious in knowing is this.
How noise they are?
How is their lifespan and durability?
