## Questions & Answers

**Q: Are there sharp edges or are the pieces rounded?**
A: The pieces are all rounded. Very safe for Corydoras and other bottom dwellers. More like large sand grains than gravel.

**Q: Any effect on ph?**
A: None...is pH neutral, will not affect it.

**Q: Is River of Doubt gravel or sand? Would it be safe/comfortable for corydoras?**
A: Its like a mix of both. The black is tiny gravel and the whitish is finer sand like. I love it. Careful when vacuuming though
