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..
Red Sea’s Algae Control Kit includes high accuracy colorimetric comparator tests for the exceptionally high accuracy measurement of nitrate and phosphate.
The nitrate & phosphate tests are essential for the accurate dosing of Red Sea's NO3: PO4- X (biological nitrate & phosphate reducer) which is part of the complete Red Sea Reef Care Program.
Red Sea's Marine Care Kit includes easy-to-use tests for the accurate monitoring of all of the important parameters during the biological maturation of marine and reef aquariums and beyond.
Red Sea's Coral Colors Pro Kit includes advanced tests for the high accuracy measurement of iodine, potassium and iron. All of these elements are associated with many biological functions, including coral pigmentation.
This test kit enables accurate dosing of three of the Coral Colors Supplements range, which are part of the compete Red Sea Reef Care Program.
Red Sea's Reef Foundation Kit includes high accuracy titration tests for the accurate measurement of the elements calcium, magnesium and alkalinity (KH) which are the basic foundation elements of coral skeletons.
All of these elements need to be available in balanced proportions for sustainable successful coral health and growth.
This test kit enables accurate dosing..
Ammonia and ammonium should be rapidly converted by aerobic nitrification into nitrite and then nitrate and finally into nitrogen gas. If this does not happen then either the aquarium is not fully matured or there is a problem with the tank`s biological system, which can be caused by an excessive biological loading being placed on the system.
The Salifert Ammonia Test Ki..
Calcium is a major constituent of coralline algae, the skeletal material of hard corals and the skeletal needles of soft/leather corals. In many cases too low a calcium concentration retards coral and coralline algae growth.
Calcium also fulfills many important biological functions.
In a healthy aquarium, the growth and multiplication of corals, calcareous algae and ..
Copper is often used as a treatment for parasite infested fish and it is essential that the correct concentration is used as too high levels can be toxic to marine fish and invertebrates.
Tap water can also be naturally high in copper and it is therefore advisable to test for this on a regular basis.
The Salifert test kit offers a very sensitive and accurate test..
Iodine is present in natural sea water in a very low concentration (0.6 mg/L or 0.06 PPM) and this iodine occurs as several different species including iodide, iodate, molecular iodine and hypoiodite.
There is a misconception among many hobbyists that iodide predominates in natural sea water but in fact, it is iodate which is the predominant element.
Test kits which ..
Calcium is not the only substance needed to form the skeletal material of corals and allow calcareous algae to grow. Carbonate and bicarbonate are also needed and these two substances can have a major effect on stabilizing or buffering pH levels in the aquarium in the correct range of 8.1 to 8.4.
The total carbonate and bicarbonate concentration is also called alkalinity..
Magnesium is present in natural sea water in a fairly high concentration (1350 - 1500 mg/L) and is an essential element of chlorophyll which is necessary for photosynthesis. Without photosynthesis plants, algae and coral would not be able to survive.
Magnesium also helps to maintain the correct combination of calcium concentration and alkalinity as it slows down the form..
When there are insufficient areas of a tank which are deprived of oxygen (anaerobic zones) or denitrification is not taking place properly, nitrate will build up. This can also happen in an aquarium where the biological loading on the system is causing an imbalance e.g. if there is excessive livestock for the aquarium volume or over feeding is occurring.
The build up of ..
