Liquid pH buffer and carbonate hardness supplement

For good coral growth, saltwater aquariums require optimum buffering with stable carbonate hardness between 7 and 9 °dH. Fluctuations in the pH value, as for example in the case of excess acidity due to excrement and decomposition processes, quickly cause stress and diseases in all the aquarium inhabitants, thereby shortening the life of the young animals. Tropic Marin® LIQUID BUFFER effectively increases the carbonate hardness and stabilises the pH value at an optimum range between pH 8.1 and 8.4.


Helps quickly and reliably if the pH is outside the recommended range of 8.1 – 8.4
Kicks in if sediment has reduced the alkalinity and thus the buffering capacity of the water
Reduces the stress for all aquarium inhabitants with more stable water conditions
Suitable for an aquarium stocked with marine fish, soft corals, LPS, SPS, other filter feeders and/or crustaceans
Easy to apply – suitable both for manual dosing and for dosing pumps


How to use:

Regularly check the carbonate hardness and pH of the aquarium water. In saltwater aquariums, carbonate hardness should be 6 – 9 °dH, with a pH value from 8.1 to 8.4.

If significantly different values are measured (pH less than 7.7 or greater than 8.6 / carbonate hardness under 5 °dH), use 30 ml (2 Tablespoons) of LIQUID BUFFER per 100 litres (26 US-gal) of aquarium system volume, thus supplying about 0.8 °dH. Repeat daily if necessary. Do not exceed a carbonate hardness of 9 °dH.

1000 ml LIQUID BUFFER contain 2,800 °carbonate hardness.

Use the new dosing calculator for an easy determination of the required amount of dosage for your aquarium.

To regulate the pH and buffer capacity, while at the same time adjusting the level of trace elements, we recommend the crystalline Tropic Marin® TRIPLE BUFFER.
