I have observed something similar in my tank, except mine is a green film which only affects where the substrate is.

From what i believe i think it is either excess nutrient(s) you dose not being used by the plants and thus setteling into the soil itself. Possibly?

Another alternative i have thought of is that it is just algae growing between the substrate and just visible at the tank edge. Possibly?

If anyone has any ideas on what it could be for sure would be appreciated Mine is only guess work...

Can be remove quite easily. But may stir up the dirt. You may try to cover it outside the tank with oyama paper.

I believe that's a common result of algae growing on tank glass... just that Otos and Snails can't reach this part Is your tank getting daylight from nearby window?

To remove them... you can try using a blade (those used for traditional shaving)... slide it into the soil at an angle. It will come off as a film... very satisfying

Settlement of fish/shrimp poo, base ferts, or debris and part of bacteria colonize area, also will have some slight algae grow. Current flow circulation play a part also, as the soil or gravel have gaps in between. If you stir it, you'll disturb the ecosystem and may wipe out your fauna sometime.

What I did was merely push a ruler just between the glass and soil, and the algae will be buried inward and hopely suffocate itself

[Verminator]

Zenscape that is exactly the technique i use Except i scrape it off and stir it up to siphon it out. So long as i do it slowly, and just around the base inch or two i don't stir up unwanted toxins.
