## Questions & Answers

**Q: What media bags are appropriate for this product (in terms of mesh opening size, measured in microns)?**
A: Great question! We recommend what is called a “Fine mesh bag” of 100 Microns or higher rating for rinsed media placed in a filter unit.

**Q: How do I calculate how much to add without weighing it if I don’t know the density?**
A: Hello, thank you for your question. For the GFO HC, there is approximately 15 grams per Tablespoon by volume, so 1 tablespoon would treat 7.5-15 gallons.

**Q: Can it be regrnerated?**
A: Thank you for the question! We do not recommend regeneration of the GFO. If you have any other questions, please let us know!
