Wave Currents

Is it important for the wave currents to be alternating or can I have a powerful current circulating the tank?

Waves are cool and more natural and they have gadgets that create that, but most of us go for a good constant current created from power heads.
The most important thing is water movement with no dead areas where no flow is located.

Whenever possible, it's best to avoid constant laminar flow. Wave boxes and dump boxes are unsightly and have also been known to blow out tank panels from the constant waves pushing against them (this is especially true of large panels), but you can use other means, such a SCWD's (I'm a huge fan of these), or any of the various electric/electronic wave makers.
Another way to get some semi-random current flow is to aim two or more returns so the flow patterns crash into each other, thus making random flow patterns and eddies.

Alright thanks, how many gph is optimum? I bought two 1400 gph Koralia Evolution's for my 75 gallon and now I think both might be too powerful. A lot of the corals close up and my clam doesn't seem to like it either.

I have 1 1400 koralia, 2 550's and 2 #3 korallias and still want a bit more in my 55g.

You really need to experiment with directing your flow. Also, is this a reef tank or FO setup? The flow will usually be different for each type of tank.

I usually play with my flow when I set the tank up, then make adjustments as things progress. During the cycle, you can use a bit of flake food or frozen artemia in the water to observe the flow patterns.
