FAQ: Will Seachem Discus Buffer® affect my pH, GH, or KH?

Yes! Discus Buffer® is intended to alter the pH and will raise the buffer concentration in your aquarium.  This raises the alkalinity of the water, which your water test may report as a rise in KH.  Discus Buffer® will also soften water by precipitating minerals, so you may see a noticeable drop in GH when using this product.
