## Questions & Answers

**Q: Will this work in freshwater aquarium**
A: Yes, it will remove phosphate from freshwater.

**Q: How does this compare to the gfo from brs?**
A: Similar, looks the same. My Phosphates are at 0 so it is doing its job. I change it every three weeks so not sure about longevity, I think the BRS product only needs to be changed every 2 months, so that may be something to look into.

**Q: Can this be used in a fresh water tank with a sump?**
A: Yes, this will work in freshwater with a sump.  You will want to place the GFO in a mesh bag or media reactor, to keep it contained.

**Q: How often should you change the GFO out?**
A: Check your phosphate. When the phosphate goes up change it out. You want it to be low but not zero. You will get cyno blooms then.
