Hi everyone - I have a 60g cube that *should* be arriving some time in October. I’ve had a number of freshwater tanks but am new to the reef game. Been trying to research powerhead options and seem to have settled on the Nero line as they seem to offer plenty of flow and customizability for far less than the Ecotech MPs. My question is whether I need 1 or 2 and if it’s worth going for the Nero 5 or sticking with the Nero 3. I’m going to assume most people will recommend I buy 2 as that’s what I see on many pictures of tanks of this size. However, my default would be to get 2 Nero 3s. Is that short-sighted? Should I get 2 of the Nero 5s? Thanks!
