## Questions & Answers

**Q: How much volume does of this stuff is 1 gram. Am I supposed to weigh it out on a balance?**
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: is it cheaper than the one sold by BRS ?**
A: If you  figure cost per pound  BRS is still  cheaper.

**Q: Q granulometria tiene? En reactores se mezcla con carbón?**
A: Hello, thank you for your question. This product has fine granules similar to carbon, but finer.  It can be mixed in reactor with carbon or used by itself.

**Q: I want to know if these work for reef tanks and if they are more fine dusty or larger sized pellets?**
A: I use these for my 125 gallon reef tank.  They work great. They do need to be rinsed before you use them. They are a little dusty. But I've had worse.

### ⭐⭐⭐⭐⭐ Keeps phosphate down better.
*by S***8 on September 12, 2024*

### ⭐⭐⭐⭐⭐ Good grain size. Minimal dust.
*by I***Y on June 11, 2022*

Container was filled correctly (as compared to the reviews/complaints with the 2 little fishy's GFO). Grain size is good. Rinsed with RO/DI water in a mesh bag a few times to get the dust out. Initial dose is 1 gram per gallon. 1 tablespoon = 8 grams. Maintenance dose is about twice that amount.
