Marine Buffer will raise marine pH to 8.3. IN cases where low PH is persistent this product will effectively raise the PH levels.

INSTRUCTIONS:
** Note that any changes of PH should be done extremely slowly to avoid shocking the animals.

It is preferred to use this product in new water change water only.
Otherwise, you can mix a small amount of the product (1/8th of a teaspoon) in a cup of saltwater. Once dissolved the solution can be added using the feeding pipette a small amount at a time. Adding the product directly into the aquarium with animals can harm them is a sudden change in PH occurs. Check PH frequently and aim to slowly bring up the PH level over a number of days. 

After this new water can be buffer to 8.3 prior to using for a water change.
