Malawi/Victoria Buffer

  • Buffers to pH of 7.8 - 8.4
  • Raises KH as well pH
  • Will not affect GH


Malawi/Victoria Buffer™ is a blend of carbonate salts designed to enhance the natural environment of cichlids by increasing carbonate hardness, buffer capacity, and pH. It is formulated to maintain a pH of 7.8–8.4. For optimum replication of the Malawi/Victoria Lake environment, use with Cichlid Lake Salt™, Cichlid Trace™, and NutriDiet® Cichlid Flakes.


DIRECTIONS: Use 6 g (one level teaspoon) for each 40 to 80 L (10 to 20 US gallons) of water each day until desired pH is attained and maintained. Thereafter, use as required to maintain pH, usually no more than once every two to three weeks. For precise dosing, use the Seachem Digital Spoon Scale.

TIPS: It is best to dissolve the buffer in freshwater before use. Use when setting up an aquarium or making water changes (preferably after the addition of Seachem’s Cichlid Lake Salt™) and between water changes as needed to maintain pH. Seachem’s Malawi/Victoria Buffer™ is formulated to maintain a pH between 7.8 and 8.4, depending on the amount used. To attain a lower pH than 7.8, you may use Seachem’s Acid Buffer™ in combination with Malawi/Victoria Buffer™. To attain a higher pH than 8.4, use Tanganyika Buffer™.

A: Ideally, the pH of the environment should be adjusted accordingly before introducing your first fish. If this is not possible, then I recommend to add the product slowly until the desired pH is reached if there is fish already in the aquarium. I recommend using Malawi/Victoria Buffer instead of Tanganyika Buffer as they are a different blend of salts. The ingredients in Malawi/Victoria Buffer will result in a pH between 7.8 - 8.4. The ingredients in Tanganyika Buffer will result in a pH between 9.0 - 9.4. Once the pH is adjusted to the desired range and you perform regular maintenance/partial water changes, you should exchange some of your existing 9.0 pH water for freshly mixed 9.0 water. If you do not have the ability to pre-mix water with Tanganyika Buffer or Malawi/Victoria Buffer and Cichlid Lake Salt before performing partial water exchanges, then I recommend to do smaller increment partial water exchanges and mix the buffer and salt directly in the aquarium as you do not have any other options. Be aware that Malawi Cichlids prefer a pH in the range of 7.8 - 8.4.

A: The directions are designed for use with DI or RO water. If you are using untreated water as your source water, this will, depending on how hard the water is, influence the final parameters. When both Cichlid Lake Salt and Malawi/Victoria Buffer are used as directed in relatively pure water, the water parameters will approach very closely the parameters of the native lakes. If other sources of minerals are present, such as untreated source water or a dissolving substrate (e.g. aragonite), then the conditions of the lakes will not be duplicated as closely, since there is/are unpredictable variable/s. While a pH of 8.6 is a bit higher than targeted by these products, I expect the pH will likely settle down to something closer to 8.2 – 8.3, even if other sources of minerals are present.
