leave all powerheads on 24/7?

[manaf]

so i was thinking of turning off my koralia 4 and 3 at night and just leave 2 koralias running at night? just for the fish to relax a bit? would this harm anything? i dont got any serious corals that require alot of flow just some softies

and i dont have the money to get a wavemaker

thx for the help!
