KH Buffer Block Large will stabilize the pH automatically and increase water alkalinity in your pond. As your pond water becomes acidic our buffer block will release buffer KH. Low or no buffering capacity (low alkalinity & calcium carbonates) causes the pH of the pond to become unstable resulting in wide swings of the pH.
KH Buffer Block adds essential calcium needed for healthy fish bone growth. It also enhances the growth and survival of beneficial bacteria for a healthy, beautiful pond. KH is a MUST for proper biological function as well as water clarity!
Large Block: 2,000-10,000 gallon pond
