With a 30" tall tank you'll be able to mount the VorTechs higher and there should be minimal sandbed disruption, if any. I think the top of my MP40s are about 3.5 inches from the water surface on a standard 24" inch tall 4 foot long 77 gal tank. I also run them at about 85%. If they were mounted any closer to the surface, they would probably be pulling little air tornados (vorteces) from the surface. You've got an extra 6 inches of height and 3 feet of distance to the other glass, so depending on the depth of your sandbed, you should be ok. The flow pattern of VorTechs broadens quickly as distance from the nozzle increases. Another reason the pointing issue as with other power heads is really a non issue.
