I am using two Tunze 6045 Nanostreams one mounted on each side of the aquarium. I am using these since the this tank contains contains LPS & Soft corals and they do not like a lot of flow. Hope this helps.
We found a baby Hammer coral attached and growing on a rock in our tank. It was discovered after we removed the mother colony which was sold this past weekend.
