The Red Sea Coral Buff maintains a high buffer capacity & stable pH in reef aquariums.

The pH of natural seawater remains stable due to its nearly inexhaustible stock of dissolved alkaline buffer substances such as bicarbonate, carbonate and borate. In a reef aquarium, buffering substances are constantly consumed as part of the calcification process by corals, calcareous algae and other invertebrates and should be replenished on regular basis. A low alkalinity may allow a sudden fall in pH which would be very dangerous to all organisms in the aquarium.

For best result reef aquariums should have an alkalinity of 2.5 - 4 meq/L (7-11 dKH,) and a stable pH of 8.2 -8.4. Check the alkalinity of your aquarium weekly with Red Sea’s Alkalinity Test Lab.

Recommended for use in conjunction with weekly 10% water changes.
