black sand questions

The ad says it absorbs ammonia; is there any way to "recharge" the black sand, I.e. get rid of the ammonia it sucked up, so I can reuse it? Or does it stay stuck?

Do I have to replace it regularly, or is it ok to just leave it as is, sans ammonia sucking properties?

What is it exactly? It absorbs ammonia, balances ph, so I'm guessing it's some sort of zeolite/fluorite.

Finally: the stock I saw didn't look al that new; does the ammonia absorbing/ ph balancing properties fade out over time?

I have no experience with a product like that, but I have to wonder the point.

Bacteria will consume all the ammonia in a tank anyways, and a product like that would starve that bacteria and thus create the problem of having to use that product (and pay for it) forever with the constant risk that it will 'run out' and cause an ammonia spike that hurts/kills your fish.
