Life has been getting in the way of posting lately. It has a habit of doing that.
My new Koralia 3 power heads have been installed and are running. If I had to do it again I would have ordered the 2's. The current generated by the 3's is on the high side. I knew I had to adjust the aiming when my wife commented that my torch coral looked like it was going for a ride in a convertible. They are aimed at the surface of the tank along the back glass.
