How much flow is too much flow?

ahhhh, first "real" post since the return.

Alright, if your tank is anything like I remember hex's to be it's a taller tank, so you'll need to keep that in mind when it comes to things like coral placement, lighting and of course, flow.

What kind of corals you plan on keeping will determine just how much flow you're going to need/want.

For softies/lps you could realistically get away with a larger, powerful powerhead (think Koralia 2 or 3) placed lower in the tank to provide an upward/circular current and your return pump to pick up the slack near the higher parts of the tank. If you're going the SPS route, you'll need more flow, alternating currents and a strong light source...so even though you may be in the early stages of planning this reef out, a final picture is needed so we know what you're shooting for.

Welcome to reefing, may the gods have pity on you ha ha ha
