I recently added some Reeflakes sand to my 330g tank (got sick of the bare bottom look), and I'm glad I did - looks so much better. But of my three powerheads (2 Jebao RW-20s and a Sicce Voyager), two of them were pointing downward and of course now they have pushed the sand right out of the way, leaving piles of sand and then cleared away spots down to the acrylic bottom of the tank.
I've tried redirecting flow in various ways, but these powerful pumps pretty much bulldoze sand... So I think I need to replace at least one of them with something that disperses water in a wider flow pattern. I had Vortechs on my 90g reef and loved them - they sent flow everywhere and didn't disturb the sand at all. Unfortunately because of the way this tank is set up, I don't have room for the large exterior magnets on the Vortechs so can't use them. So I was thinking about the large Maxspect Gyre. The magnet on the Gyres can only accommodate 3/4" glass/acrylic. My tank has 1" walls, so I'd need to place it on my overflow box, near the top. I believe I've seen diagrams of these placed close to the surface, but I'm not sure how close is too close. If I put it 3" below the teeth on the overflow box would that be far enough below the surface?
