In a healthy aquarium growth and multiplication of corals, desired calcareous algae and other organisms results in calcium depletion. Because of the importance of calcium timely corrective measures would have to be taken. For that purpose a proper calcium additive together with an accurate test kit are required. Our calcium testis capable in resolv..
Flatworm Exit itself is quite safe to fish and invertebrates. However, the body fluids of flatworms can be toxic to some reef inhabitants when present in a too high concentration. This body fluid is sometimes excreted when flatworms die. So when you use this product, it is important to do the following first: Siphon out as many flatworms as p..
Salifert's Natural-Iodine additive is highly concentrated and contains a large portion iodate and also some iodide. Salifert stands alone in offering such an advanced and well thought formulation. Measures iodide and iodate (together with hypoiodite and molecular iodine) in separate steps. Similar to The Red Sea Iodine test kit...
Calcium alone cannot form the skeletal material of corals and allow calcareous algae to grow. Some other substances are needed as well. A few other constituents are carbonate and bicarbonate. These two substances also have a major impact on the stabilization of the pH in the proper range of 8.1 – 8.4. Such stabilization is called buffering. The tot..
Magnesium is present in NSW in a fairly high concentration (1300 - 1400 mg/L). Magnesium is an essential part of chlorophyll, which is necessary for photosynthesis. Without photosynthesis, plants such as algae and corals would not be able to live. Magnesium has another important function in maintaining the correct combination of calcium concentrati..
When an aquarium has insufficient regions deprived of oxygen (= anaerobic zones) or denitrification proceeds incompletely then nitrate will build-up. A too high nitrate concentration can result in unwanted algae-growth and these might irritate corals in their neighborhood. Nitrate as such also retards coral growth. The nitrate concentration in a pr..
It is a misconception that once a tank is through its cycle (first 3 or 4 weeks) that nitrite has vanished. Many nitrite test kits suffer from interference by amines (such as naturally occurring and essential amino acids) resulting in a too low measured value especially if the nitrite concentration is relatively low. Nitrite is converted to nitrate..
The pH value can have a major impact on the growth of corals and calcareous algae and on many biological processes. The pH should not be allowed to fluctuate more than approx. 0.3 units during 24 hours and should preferably be kept between 8.0 and 8.2. If the pH is too low then the cause may be a too low alkalinity and/or insufficient aeration. A..
Phosphate has several negative effects if present in a too high concentration. First of all undesirable algae growth might result. Making an aquarium an unpleasant sight. Phosphate also blocks or retards the growth of corals and calcareous algae. One of the scientific studies shows that a phosphate concentration higher than 0.05 mg/L decrease..
Potassium concentration in natural seawater is approximately 400 ppm. Many aquarists have reported that a low potassium value reduces colors in corals. This can be corrected by increasing the potassium value to the normal natural concentration. Now you can accurately measure this value with the new Salifert Potassium Reef Test kits. Whats Inc..
Salifert Strontium Profi-Test In a marine aquarium strontium plays an important role in accelerating the growth of coral and calcareous algae and natural sea water contains approx. 7 - 9 mg/L strontium. Strontium is very difficult to test for, but if there is found to be a depletion of calcium in the aquarium then strontium levels are likely to be..
