Is this gonna be too much flow?

I have a 6 gallon fluval edge. I couldnt remember the flow rate for this powerhead, bought it a long time ago. The lowest rate for what I think is the same model, the hydro koralia, is 600gph. The 1050/1150 seems familiar and it sounds like what I would've got, so I assume the flow for this powerhead is 1050gph

Oh man as soon as you plug it in, it will look like that tank got hit by a tornado.

You can always tell by your sand blowing. I go to the point to where it moves and back it down by 10 on my MP40s.

You need the smallest nano koralia at most, even that might be too much at 240gph

I use a mj1200 as my return and only source if flow in my 13.5 and it’s a very heavy flow. Sand bed shifts fairly easily. I would go lower flow
