Agreed, Slow flow is better for some species of fishes.I switched out Emperor for aquaclear's for 55 gallon pleco tank .Tank is filtered with Aquaclear 110 and aquaclear 70 along with aquaclear 802 powerhead attached to Aquaclear Quick filter and Hydro sponge filter that was /is being used as seed material from established ,disease free aquarium.
Tank currently houses one LDA 31 pleco,one L104 pleco,one L201 pleco, and three juvenile Bristlenose plecos.These fish appreciate currents in the aquarium and the current also serves to keep particulates and waste in the water column longer for the filter to catch.
I have two Emperor 400's on 75 gallon work tank housing six loaches approx five inches long, and one adult electric blue jack dempsey that is approx eight inches long, Water movement and lot's of it are appreciated by the loaches (not so much the dempsey).
My planted 80 gallon tank with approx eighty small assorted tetra's,barb's,corys.is filtered by one eheim 2217 which provides not too much current for fishes that don't really need or appreciate it.
both the emperor and aquaclear filters are excellent choices in my view for HOB filters and flow can be adjusted on both .
