Good luck. **Q: Is this 2 8oz bottles? 1 16oz bottle? 2 16oz bottles?** A: Use 3 ml only **Q: How much does 16 ounces treat?** A: Add 10 ml. per 10 gallons of aquarium water.

So math says roughly 47.31 gallons can be treated with 16oz. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by W***H on 30 May 2023* This works great and great price ### ⭐⭐⭐⭐⭐ Review *by C***G on 9 June 2025* Great ### ⭐⭐⭐⭐⭐ Review *by W***Y on 4 November 2023* Needed it for starting up a 75 gallon aquarium with a canister filter.
