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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Product *by L***S on August 17, 2025* Great Product ### ⭐⭐⭐⭐⭐ Keeps phosphate down better. *by S***8 on September 12, 2024* I was using the regular GFO from this brand and from an aquarium website.
