Thank you **Q: Can it be used in gray and black tanks the same way?** A: We really don't know about the use/purpose in the Gray tank, definitely in the black tank. Why not just something like Dawn dish detergent in the Gray tank? Just a thought, it's a good degreaser. **Q: This product uses 8oz single use bottles and another company has 4oz single use bottles. Which do you need?** A: My tank is 50+ gallons. I tried the 4oz version with poor results. Switched to the 8oz bottle and it works just fine. **Q: Is liquid blue** A: Cypress sent is green in color ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome tank treatment *by on Reviewed in the United States 17 July 2026* This is the only tank treatment we use.
