Power Head

So I was instructed at my LFS that the mover m1900 2 pack would be perfect for my 75 gallon tank no sump. Seems like my 2 clowns seem to really be working sometimes. I’ve ready that 50x what your tank is so these 2 would be 3800gph. Just wanted to make sure wasn’t making them overwork and stress them out with just adding them to my tank.
Thanks!

I never heard of them so had to look them up.
I would run the wide 120° flow and put them on a timer. Run pump one on for 15 minutes then both on for 15 minutes then pump 1 off and pump 2 on for 15.
That would be a good cycle as both are only on for 15 minutes.
You can adjust your times accordingly.
Mount them on the back
Wall and aim them at the center of the tank.
Your clowns need some areas of slow flow so some rock work can break up some of the flow and give them places to hide/sleep.

Haven’t gotten to the point of a timer for them. Will have to look into that. Any recommendations?

Check home depot or similar store for a digital one.
They work well and are not expensive.

My tank is 140L, and I use one rossmont M4600 (4600lph), M5800 (5800lph) with waver and a maxspect Jump.
Both rossmont are in the opposite sides facing each other, creating standing waves 24h, one setup. Maxspect Jump 2K (7000lph) creating additional gyre flow, programmed for 8 time points.
