Thanks for the tips everyone! I will look into these suggestions.
I hope that I can do this without tearing down the tank--I know that this would take me all day. If I can find a less toxic product what about taping a drape underneath the abovewater area to hang above the water so I can work above it on the glass? Could I hope to do this?
Oh and here's another recent shot of the tank. I was rearranging it some more. I took this picture fast after wiping down the front pane with water. You can see a bit of the milky film up along the top of the front pane.
