What is KH in an aquarium?
KH , or carbonate hardness , refers to the concentration of carbonates and bicarbonates in the water. These elements play a fundamental role in the chemical stability of the aquarium, notably by acting as a buffer for the pH . In marine reef tanks, KH also supports the growth of hard corals , which use these carbonates to build their calcareous structures. A stable KH therefore helps create a healthier and more stable environment, limiting sudden changes in pH during the day.
Why monitor the KH of your aquarium?
KH acts as a chemical stabilizer . If its level drops, the pH becomes unstable, which can cause significant stress for your fish, corals or invertebrates. Conversely, too high a KH can impair the absorption of calcium, an essential element for the growth of calcifying organisms. In a reef aquarium , the general target is a KH between 7 and 9° dKH , although it can go as high as 12° in some specific protocols. To maintain this stability, it is essential to measure the KH regularly and adjust the values as necessary.
Products for measuring and adjusting KH
KH tests for accurate measurement
To accurately monitor your carbonate hardness, choose reliable KH tests like Salifert test boxes . Available as drop-in or electronic tests like the Hanna Instrument HI772 photometer . These tools allow you to track KH variations on a daily basis. It is important to use reagents that are not expired and to calibrate your devices if necessary.
KH boosters
When the KH level is too low, adding a Kh buffer can quickly raise the level. These ready-to-use or powdered solutions are easy to dose and work effectively to restore balance.
Remineralizers for osmosis water
If you use reverse osmosis water, consider remineralizing it with a marine aquarium salt suitable for your aquarium population. Some reverse osmosis systems for saltwater aquariums are compatible with remineralizing solutions, ensuring your water is enriched with carbonates for a naturally balanced KH.
Choosing the right KH product for your needs
Every aquarium is unique, and so are your KH needs. That's why it's helpful to choose a product based on its brand and maintenance method:
For a community aquarium, the ideal KH is between 6 and 10 dKH , depending on the species kept and the desired stability. A KH around 8 is often considered a good compromise.
How to raise KH naturally?
Using bicarbonate or carbonate buffers can help gently raise the KH . Remember to do this gradually so as not to upset the overall balance. You can also implement a balling method to maintain the KH and all other aquarium chemicals using dosing pumps .
Can KH be lowered safely?
Yes, but gently! To reduce KH , water changes are generally performed with new water that is lower in carbonates. Avoid sudden drops that could stress the corals.
