## Questions & Answers

**Q: Is this ok for use in fresh water tanks?**
A: The instructions I have read say yes it is safe on both salt and fresh water tanks

**Q: Does the 1000ml size come with a filter bag for placing in the sump?**
A: Hi Michael, no the 1000 ml. size does not come with a filter bag. I would recommend to run it in a media reactor, it will be much more efficient that way.

**Q: Is RowaPhos less likley to clump than BRS standard GFO?**
A: Either one will clump if not used properly but Rowaphos is a great product!

**Q: Does this need to rinsed?  I saw some people rinse it and others don't..what are your suggestions?  i will use it within a reactor on 120 Reef.**
A: My understanding is that you should not rinse this product. I never have and have never had issues with it in my 120.
