RW-4 in a 20G

I'm kinda baffled that an rw-4 is too much for a 20 gallon... The fishstreet store states that the rw models correspond as such:
Wp-10=rw4
Wp-25=rw8
And so on....
The flow should be similar. Maybe I'm wrong or ur rw4 has a supercharger....
Even a low intensity "else" mode kicking up sand?

I've tried it on low intensity else mode... it doesn't kick the sand up but eventually the area under the pump is cleared of sand right to the bottom. I have caribsea fiji pink sand.

It might be the positioning of my pump or may need to be in a taller tank. I think the rw4's are great though. They push a lot of water around.

The rw4 are equivalent to wp10's but the design of the pump casing is different.

I think I'll give the RW-4 a shot and get the adjustable power supply at the same time so I can dial it down further if needed.
