Well my thoughts -
If you run your vortechs at 50% power, they are very quiet, at 100% power, they can vibrate a bit and be noiser than some people like… I run 2 MP40s at full power on my 80 gallon…… but I like a lot of flow
I’d personally recommend getting 2 MP40s, that you can run at 50 or 60% power, keeps the noise level down, and then you still have room to turn them up if you think you want more flow, VS being stuck with a maxed our MP10
