Have been ordering these sponges from Revain for almost 15 years and have never had a problem. This time the 70-gallon sponges were too big β and too wide and too long β they got in, but it severely reduced water flow β gradually trimmed them to fit better, but water flow still decreased. Not sure if the density of the foam is different in this box or if it's a size issue - I suspect this box was a fake - made by Josh's Frogs.
