I can't wait for my maxspect to die do I can replace with an orbitI have 2 orbits for my 310 gallon and I LOVE the flow. I bought the bigger ones thinking ok the tank is 7' long I'll need the power but holy crap are they strong. I have them on at 15-25% random flow and that is PLENTY. LOVE that they work with the mobius app, the best app of all my tank apps in my experience.
