Buffers & carbonates adjust the alkalinity, hardness and/or pH of your aquarium water
, and aid in (keeping levels stable despite changing conditions) which is also known as "buffering". This is crucial to the survival of aquatic life, and these levels should always be monitored to help keep water conditions safe for your aquatic life.
Using products like BufferPlus™ from CaribSea will help to stabilize pH and raise carbonate hardness. The proper pH for marine aquariums range from 8.1 to 8.3. A marine reef aquarium
should maintain a pH of 8.2 to 8.3. Carbonate hardness should range from 3.5meq/L to 4.5meq/L.
