I learned that there was dust (about 4 pieces) on my camera's sensor! When I started playing with the F-45 setting I found these green looking specks in my pictures. I cleaned the front lens and tried again. Still there. Cleaned the back part of the lens. The dust was still there. Double checked that it wasn't the aquarium glass (twice). And when all else failed, I realized that I was going to have to clean the sensor inside the camera.
So with a heavy sigh, I locked up the mirror and used the bulb blower to clean the dust off of the sensor. Luckily it worked on the first shot and I was able to take dust free pictures after that! Nerve wrecking, but painless process. Glad to have that behind me!
