I thought I might add that I have a wp40 that is running in my 210gal and I am running it on H and my oolite sand is not being bothered at all. I bought a voltage regulator before I received the pump since everyone said this thing like a mp60 and might need to be toned down; that's not the case for my size tank.
Anyone on the fence about one of these being too strong remember it has a L setting that is pretty weak vs the H setting. I think you could easily run this pump on L in something as small as a 75gal without problems. For smaller tanks use a voltage regulator and it will work for just about anything.
I will probably buy a second one to use in my 210 gal and still not need the voltage regulator to lower the power.
