Liquid pH buffer and KH creators


Liquid Buffer


Product description

Liquid pH buffer and KH creator for seawater aquariums


Marine aquariums need optimal buffering for good coral growth with a stable carbonate hardness between 7 and 9 ° dH. In addition, fluctuations in the pH, e.g. in hyperacidity by excretions and by decomposition processes, quickly cause stress and disease in all aquarium dwellers and thus shorten the life of the nurslings. Tropic Marin® Liquid Buffer effectively increases the alkalinity and stabilises the pH in the optimal range between pH 8.1 and 8.4.



  • Helps reliably and quickly when the pH is outside the recommended range of 8.1 - 8.4

  • Controls when precipitations have lowered the alkalinity and thus the buffering capacity of the water

  • Reduces stress for all aquarium dwellers through more stable water conditions

  • Suitable for aquarium stocking with marine fish, soft corals, LPS, SPS, other filters and/or crustaceans

  • Easy to use - suitable for both manual dosing and dosing pumps



carbonates and bicarbonates


Application & Dosage

Regularly check the carbonate hardness and pH of the aquarium water. The carbonate hardness should be 6 - 9 ° dH in the marine aquarium, the pH between 8.1 - 8.4.


If the values ​​are significantly different (pH less than 7.7 or greater than 8.6 / carbonate hardness less than 5 ° dH), add 30 ml of Tropic Marin® Liquid Buffer per 100 l of aquarium water, which will deliver approximately 0.8 ° dH. If necessary, repeat the application daily. A carbonate hardness of 9 ° dH should not be exceeded.


1000 ml of Tropic Marin® Liquid Buffer supplies the aquarium with 2800° of carbonate hardener.

Other product recommendations

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.

The very accurate, straightforward Tropic Marin® water tests KH/Alkalinity-Test or pH-Test (for seawater) are suited for checking the quality of the water and the essential parameters.
