This boosts the KH so that doesn't happen. It's not an issue if your water already has enough KH. **Q: Is there an expiry date for alkaline buffer powder? ?** A: Cannot see any expiry or use by date at all. **Q: How quickly does this raise the ph in the tank** A: Very quickly, you need to use something like a measuring jug and then scoop out some tank water add your required amount to the jug mix thoroughly then dribble the contents back into the tank. Try to take as long as possible adding the solution back to avoid pH shock to the inhabitants ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works efficiently and perfectly *by L***A on 10 October 2025* This product works extremely quickly and perfectly.
