2-6060s in a 90 gal

[India]

I've enjoyed simple loop circulation with one 6060 in my 90 - I simply wedged it in a rear corner, pointing down the back...As my livestock changed, I wanted to kick up the circulation a bit, and I purchased a second unit. I'm trying to think of ways to arrange them in a fairly full tank...The reef is dense at one end, a bit lighter at the other end, and rather open with bridges in the middle...I'm thinking of locating them behind the denser area (it would be about a third of the way down the length of the tank) and stacking the two units, pointing in opposite directions (I just kind of wedge them in the rock work.) I think this would minimize dead spots at the ends/corners. Any thoughts/different ideas, please?
Thank you very much,
India

Just be sure you can remove them for cleaning. The tolerances are tight, that is how we achieve the high energy efficiency and they should be cleaned at least every 6 months. The flow is diffuse so it doesn't move through obstacles too well. I would consider placing one on each end and having them on timers with 1-2 hr off and on intervals so they are on at opposite times and during daylight hours an overlap of 15minutes or so occurs to create a surge.

Thank you for your help...
My concern about alternating them (aside from wearing out the pump) is that fish and inverts can enter the pump while it is off, and get hurt when it starts up...

Wear isn't a big issue if you stick to 1 hr intervals but if you have small fish this could be a problem.
