Re: [APD] Clear for Life Aquarium Problem

If you want to get really radical, consider the stuffs used
by woodworkers for highly polished surfaces. These include,
beside the car polishes, various abrasives, all the way
down to sheets the abbrasiveness is the equivalent of a
human finger (which I think is equaivalent to about 30,000
grit).

The stuff listed here:

and here

only goes to 12000 mesh, but if you hunt around you might
be able to find finer.

I'd as the tank manufacturer what size grit they used to
polish the tank so you have some idea of how fine you need
to go to get beyond visibility.

There's a very brief summary on grits (the inedible kind)
here:

Even with power tools, polishing takes a lot of patience
and elbow grease. My favorite comment about polishing is,
"After you are finished you will be able to look at the
surface and easily see yourself and you will look very
tired.

good luck,
