Marine Power Easy KH

£18.00

Marine Power Easy KH/Alkalinity is required to raise the level of KH – alkalinity (bicarbonate level) in a marine aquarium. Its formula has been designed for smaller tanks occupied mainly by soft corals. The active element of the product is a substance that increases the alkalinity of water. The product also contains small amounts of potassium, iodine and fluorine.

Description

KH (alkalinity) is one of the most important parameters of the saltwater in a marine aquarium and it depends directly on the level of bicarbonate anions (HCO3-). The higher amount of these ions in the water, the higher KH. Bicarbonate ions play important roles in the stabilisation of the pH level of seawater, which is almost constant in nature. Unfortunately, in home aquaria, pH is subject to daily fluctuations caused by low levels of KH. Bicarbonate ions are also the main source of building material for coral skeletons, the basic component of which is calcium carbonate CaCO3. It is thanks to the appropriate level of KH (bicarbonates) that corals grow.

The alkalinity of reef coral waters is about 7 dKH. In the majority of home marine aquaria, a stable level of 7 – 10 dKH should be maintained. It is not recommended to raise KH too high, because it can be dangerous to LPS and SPS corals, and also negatively affect bio-filtration processes.

In a healthy marine aquarium, the level of the bicarbonate ions (HCO3-) is constantly decreasing, mainly due to the consumption of calcium carbonate during the calcification process. Carbonates are consumed not only by stony corals (SPS and LPS) but also by molluscs (snails, bivalves) and coralline algae. The loss of bicarbonate should be regularly supplemented with Marine Power Easy KH/Alkalinity. Consumption of HCO3- depends on many factors, such as water temperature, lighting, type of stock in the aquarium etc., and their level requires regular control.

If mainly soft corals are kept in the tank, the daily KH loss may be small and may be different every day, therefore we recommend calculating the average daily KH drop (bicarbonate consumption). To determine that, two measurements of KH should be made with an interval of 4 – 5 days. It is important that both tests are made at about the same time of the day and that water changes (if done every week) are made at least 24 hours before or after the tests. This way, they will not affect the results. In a healthy aquarium, the first KH score should be higher than the second. Then we subtract the second result from the first, and divide the obtained value by the number of days (minus 1), between the two tests.

The dosage of Marine Power Easy KH/Alkalinity depends on the daily KH loss. One full cap of the liquid (about 20 ml) will increase KH by approx. 0.53 dKH in 100 l of water.
