Hey guys! I just set up a new 29 gallon tank and I went out and purchased a tetra whisper ex 70 as my filter. It’s rated for 340 gph. It seems that this filter is way to strong for my fish though. My tummy noses and cardinals are being washed all over the place and even my gudgeons seem to be struggling. At the moment I replaced it with my Marineland penguin 150 and the tetras are doing better. How do people run these bigger filters without affecting their fish??
