Calcium is the primary building block of corals, clams, calcareous algae and many other organisms that we grow in our aquarium. Without adequate supplies of calcium these organism will not flourish and will eventually waste away and die.
The ideal value of calcium for a marine aquarium is between 380-450 mg/Lt (ppm) and for planted freshwater aquarium 100 mg/Lt (ppm). Be..
The alkalinity of a solution refers to its capacity to buffer against drops in pH. It is a measure of the concentration of various negatively charged ionic compounds (anions) such as carbonates, bicarbonates, borates and hydroxides in the aquarium water. The concentration of these ions determines the buffering capacity of the water to maintain proper pH. If the percentage of..
Magnesium (Mg) is present in a high quantity (1300-1350 ppm) in natural seawater. Contrary to its not only quantitative significance, this element was ignored as an important parameter of the marine aquarium for a long time.
We know today that Magnesium creates a remarkable improvement in the growth of calcareous algae and also has a positive influence on the growth of i..
Phosphate (PO4) build up in aquariums appears to be a fairly common problem in freshwater and saltwater aquariums. They are present in most tap water supplies and are also introduced to aquarium water through fish waste, uneaten fish food, and decaying plant and invertebrate material. Hobbyists end up with rising levels of PO4, leading to the appearance of algae that start t..
