VorTech vs. RKE or RKL and Koralia

They take awhile to quite down but after a week or two you ought to be good to go.

Good to know. I thought maybe they needed some break in time.

One more thing, if I crank them both up full blast, it's a crazy amount of flow! So much that it causes a sand tornado below them. They're about 22-23" high in my tank. Of course, I don't run them full blast. So far, I like the "lagoon random" mode. My large GSP in the center of my tank looks incredible with the random flow going over it. I have them on opposite sides of the tank. It's super cool that they work together (wirelessly!!). I really don't think I need two more but I want them so I can keep two higher up and two lower. Then just run them at 1/3 or 1/2 speed.

Yes it seemed like they needed a little tweak at first a lot but then after a couple of weeks they're perfect and super quiet.
