it actually created a hollow spot in the sandbed at the center bottom of the tank, and my LPS would not open up fully
Tell me about it.

Yes, and one last thing. You absolutley have to have an easy way to turn them off for feeding, or the food will be surfaced skimmed and down in your sump before anything can eat... LOL

When you set up that next tank I'd consider using a wave box of some sort. I think they are ugly in a tank, but I have to admit they really do move water back and forth. Who knows you may end up throwing out your mods after you get a wave box.

ps- can you tell I'm asking for a wave box for Christmas this year

Well it's been my anecdotal observation in my tanks that having lots of steady (however you'd like to describe it) flow ranked a 10 in the importance scale, while converting this steady flow to be more random ranked a 2. I would have ranked it a 1 but aesthetically I like the look that the random flow produced.
I realize I'm likely standing alone in this opinion because every speaker we bring and every article I read preaches random flow.

Jon- I'm still not sold on random.
(obviously since I don't use it) "Alternating Laminar Flow" that is the term baby, oh yah. That's what you're shooting for.

But can't you have too much flow if it's in the wrong direction? I've lost 2 LPS' because their tissue was blown right off from too much flow.

Yep, true dat. That's why you want your entire tank sloshing back and forth.... regardless of what Jake's overy paranoia tells you about the tank walking across the room or the stand collapsing. It isn't fast flow, but it is bulk flow.

I like random. Waves crashing over a reef away from the shore and waves gently rolling into and out of the coast are two different flow patterns. the first in random and the second is laminar and alternating (with one direction -the "backwash" if you will - being a little less violent than the other).
