Do Sevs like some current??

[hamfist]

It'll be fine so long as there are plenty of places where a sev can relax out of any strong current.
If the powerhead is strong enough to cause reasonable current all over the tank, then I'd advise going for something a bit smaller for the sev's comfort.

I will take a previous recommendation, at one point, and go low on the flow.
