Product details

The Marine Buffer from Seachem is a specialized water treatment solution for saltwater aquariums that maintains a stable pH of 8.3. This product is particularly suitable for aquariums with fish and can also be safely used in reef aquariums. The Marine Buffer contains a balanced mix of sodium, magnesium, calcium, strontium, and potassium salts, which are present in the form of carbonate, bicarbonate, chloride, sulfate, and borate. These ingredients not only contribute to the stability of the pH but also reduce the precipitation of minerals. Even in the case of accidental overdosage, the pH will not rise above 8.3, ensuring safe application. For optimal control of water parameters, it is recommended to use Seachem's Multitests to regularly check the pH and total alkalinity. With a quantity of 250 g, the Marine Buffer is sufficient for up to 4000 liters of water.

  • Stabilizes pH at 8.3 for saltwater aquariums
  • Contains borate for increased stability
  • Reduces precipitation due to magnesium
  • Suitable for fish and reef aquariums.
