Need help got 2 Nero 3

[KiddoReefer]

I’m having a hard time finding the best spots for my power heads And what I should do for the settings in the app my tank going to be mostly LPS

Medium to High flow I would suggest. The Nero 3 is really crap for low flow, they Jam up at their lowest settings really easily, a single Amphipod jammed mine, out of the box two weeks in on it's lowest flow setting.
For LPS I would suggest medium to high flow from 50% to 70% ish 70 being pretty high.
I don't use the app though I just use the controller and leave it more as an inline stream pump on the preset speeds. Usually as high as I can get it without moving around sand.
