ugh! it's time for an upgrade. I'm currently running 3 maxi-jet 1200's on a red wavemaster pro. I'm actually getting decent flow in my newly upgraded 75 gallon SPS dominant reef. (upgraded from a 55 gallon) I'm just sick of all the microbubbles from the maxi's EVERY time the kick on. It's strange though, cause I didn't notice it near as much in my 55 gallon. But anyways, I'm really itching for a vortech....or two. In someones else's EXPERIENCE and not assumption, which would be the best. One mp40w, or two mp10's. I don't want one end of the tank to get blasted with flow, while the other end has lackluster flow. Oh, and I'm also leaning toward the new ES driver on the vortechs.
