Description

Hanna Checker – dKH (Saltwater) is an easy to read test kit suitable for marine aquarium keepers.

This kit is the HI-772 Handheld Colorimeter and it tests seawater alkalinity in dKH.

Reagent available for more tests: HI-772-26 Reagent – dKH

Alkalinity helps to maintain a stable pH, a vital factor for most aquatic life. Corals also need an adequate level of alkalinity in order to support healthy growth. If levels are too low, corals cannot precipitate and form their skeletons. If levels fluctuate too much or too quickly, growth can become impaired.

The more precise and stable the levels, the better the results. With regular, precise monitoring, fluctuations in levels can be quickly corrected, giving your corals the best chance of success.

Marine KH

Natural seawater has a KH of 7 – 8 dKH (or 2.5 – 2.9 meq/L which is a different unit for expressing KH/alkalinity.

Here at Cornwall Aquatics we aim to keep most of our reef aquariums a little higher than that at around 9.5 dKH.

If you need to add alkalinity to your saltwater aquarium, it is first worth checking that your salinity is correct. Most salts are now designed to be used with RO or RODI water. This means that they have a good KH content. If you have been making regular water changes with a good quality salt and your KH is still too low, it could mean that your animals are using the KH from the water to grow. In this case you will need to add some KH + pH Buffer to slowly bring the KH of the aquarium up to the desired level.
