Glass cleaning.

[John Hamilton]

This may sound silly, but how do I keep the glass clean. I have tried different cleaners and rags but I keeping getting this film that turns into micro salt crystals, sort if like snow flakes.

On the inside or outside of the aquarium?

[John Hamilton]

Outside. Otherwise I would be asking why my fish keep dying off.

We use Windex and spray it on the towel and clean the tank. Of course if you have an acrylic tank then this is not the way to go, plain RO water does well in this case.
