Question for R.B's RP-M users

[12gallonsofhex]

Hi, everyone. I am changing up the flow in my 20l from 2 sow Jebao's to a small crossflow mounted to create flow long wise, and a compact powerhead on the back wall to get some varied flow. I like the compact rp-m, but my question is, can it be turned down enough to not blow my sand bed out? Thank you for any advise!

I have a RB RP-M in my 40g cube and my sand is the sugar fine type. I have no issues with running the pump at 66% or lower.

Cool! Thank you for the feedback. I like the programmable hours with that pump. I think it coupled with a 1k gyre will get some good wave patterns for my Euphyllia and Duncans.
