The black rocks are probably charcoal.
The "danger" of tap water is the chlorine or chloramine that is added to kill bacteria. For a fish, that breathes water, it can kill them. For a turtle that swallows water, like we do, it is less of a danger.
There is still the chance that the chlorine can harm the beneficial bacteria in the tank, which is why you may consider water conditioner. One bottle of conditioner will cost more than 1 bottle of water, but that one bottle can treat hundreds of bottles of water.
Seachem Prime, one of the conditioners, just needs 1ml to treat 10 gallons (almost 38 liters). That will be much cheaper than buying water.
If your water is treated with chlorine and not chloramine, you just need to let it sit in a bucket for a few days, and the chlorine will evaporate. Chlorine instead of chloramine is much less common today, though.
