hygger Aquarium Gyre Wave Maker Fish Tank Cross-Flow Pump Adjustable Aquarium Water Circulation Powerhead with Controller Magnetic Base (2380GPH)

I have this one and it’s super easy to adjust flow. There is an up and a down button and a mode adjust button you can cycle through. I just leave it maxed on my 75 though. https://a.co/d/0aN0qere
