Seachem Marine Buffer

Marine Buffer is the safe and stable way of raising marine pH to 8.3 in your aquarium.

Marine Buffer is a blend of sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate.

Often simple sodium bicarbonate or sodium carbonate is offered as a substitute but these can raise pH to dangerous levels if not used properly.

Marine Buffer was the first buffer on the market which contained borate salts (which make a saltwater buffering system much more stable), and Marine Buffer remains the most effective pH buffer on the market for marine aquaria.

Directions:

Add 5 g (1 level teaspoon) for each 80 L.

Dissolve in at least one cup of freshwater - this dose will also raise alkalinity by about 1 meq/L.

Add daily until pH stabilizes at 8.3. This will take from a day to a week, depending on original pH and alkalinity.

Thereafter, use bi-weekly or monthly to maintain a pH of 8.3.

If this practice is not adequate, then overstocking, overfeeding, or other poor management practice should be sought as a likely cause.

In ionically balanced marine water, Marine Buffer produces little precipitate or cloudiness. If an extensive precipitate forms upon addition of Marine Buffer that does not dissolve within ~15 minutes, then poor ionic balance was present. A water change should be initiated when convenient before further use of the product.

Effectiveness improves with continued use.

Do not directly mix with any calcium, magnesium, or strontium supplement.
