Salifert Profi Test Kits for reef, marine and advanced freshwater aquarists are some of the most precise and accurate test kits on the market. Kits are available for all aspects of the aquarium's chemistry, covering organic and inorganic pollutants as well as valuable marine trace elements to allow for accurate dosing when additives are required.
Salifert pH Profi Test Kit
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 low pH can be corrected by improving aeration and by increasing the alkalinity to Natural seawater value or up to approx 25% above Natural seawater levels. The Salifert pH test kit is sufficiently accurate to monitor pH fluctuations of approx 0.2 pH units. Our KH + pH Buffer allows fast and efficient correction of alkalinity. Approx. 50 tests per kit. Range pH 7.4 - 8.6.
Salifert Nitrite Profi Test
Nitrite is a substance that is toxic to fish and invertebrates. Many nitrite test kits suffer from interference by amines resulting in a too low measured value especially if the nitrite concentration is relatively low. Nitrite is converted to nitrate in properly cycled aquariums. The thus formed nitrate is transformed into harmless nitrogen gas.
This happens in areas deprived of oxygen within live rock and miscellaneous filter materials.
Before it can be transformed to nitrogen gas the nitrate is first converted back to nitrite. When for whatever reason this particular cycle can not be completed, toxic nitrite can be present in significant concentration and readily be detected by test kits that do not suffer from amine interference. It probably is the most sensitive, accurate and fastest nitrite test kit available. The kit can perform approx. 60 measurements
Salifert Nitrate Profi test
A too high nitrate concentration can result in unwanted algae-growth and these might irritate corals in their neighbourhood. The nitrate concentration in a proper functioning reef aquarium should preferably be lower than 1 mg/L. Fish-only aquariums would usually show much higher nitrate concentrations.
Most test kits use a procedure in which a certain part of nitrate is converted chemically into nitrite and is measured as such. Once again, just as with nitrite testing, amine interference has a major impact on the measured value. If such an interference occurs concentrations much lower than actual will be measured.
Many nitrate test kits are prone to amine interference. This can give results much lower than actual. The very special ingredients allow a very fast and precise measurement. The range spans from very low to a very high nitrate concentration (approx. 0.05 – 20 mg/L as Nitrate-Nitrogen or 0.2 – 100 mg/L as nitrate ion). The kit can perform approx. 60 measurements.
Salifert Ammonia Profi Test Kit
Ammonia and ammonium are substances which should be converted rapidly into nitrite followed by nitrate and nitrogen gas. If this does not happen then the aquarium is not fully cycled or biological processes are not proceeding as they should.
The Salifert Ammonia test is very straightforward and measures the sum of toxic ammonia and ammonium in just a few minutes. The kit can perform approx. 50 measurements and can detect 0.5 ppm of total ammonia easily.
Salifert Phosphate Profi Test
Phosphate has several negative effects if present in a too high concentration. 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 decreases the growth of calcareous algae by 90%.
Washing fish food, which is a rich source for phosphates in a sieve after thawing, reduces the input of phosphate tremendously. Also avoiding use of phosphate-rich low-grade activated carbon helps keep phosphate levels as low as possible.
Checking the activated carbon for phosphate prior to use is therefore highly recommended.
The Salifert phosphate test already detects, within seconds, 0.015 mg/L of phosphate. This makes phosphate measurement highly reliable. The kit can perform approx 50 measurements.
