Power head size??????

[Rone]

Started a 15 gallon column macro tank and need more flow. I have the return pump which is up top and a small koralia nano in middle of tank. Did some research and the rw-4 seems to be to strong for it.
Want something with a controller so flow can be adjusted as needed.
Any recommedations?????

Tunxe has one I think the 4120 ? would work fine

Something like an MP10 or Turbelle 6045 should be plenty.
