Question about my 6 gallon tmc aquarium

[Wizard4s]

Hi I have a 6 gallon microhabitat aquarium which comes with a 600 litres per hour pump, I have a spare 240 koralia nano pump laying around, do you think it would be overkill? Here's a pic of my tank.

240's are pretty gentle, so I think it'd be fine. I can't tell if that's hammer or frogspawn in there, but it were me, I'd move it up one level to about mid-tank and put the PH on the rear center at the same level pointing towards one side to give a nice indirect water flow around the tank. With where it's at now, the LPS would like the flow, but the mushrooms.... not so much.

I'll try the pump and see how it goes, it seems a waste it just lying around, it's actually a type of hairy mushroom, very nice looking and it glows really green under the blues.
