Marine Aquarium Buffers
Saltwater buffers adjust the alkalinity, hardness and pH of your water to proper marine levels, while boosting your water's buffering capacity (its ability to keep these levels stable despite changing conditions in the aquarium). This is crucial to the survival of any aquatic life. Use saltwater buffers anytime you are preparing water for aquarium setup or water changes, and always monitor your levels regularly. Marine sand and substrates assist in proper buffering.
