Salifert Test Kits

• 

  Salifert Ammonia Test Kit

  Ammonia testing is mainly needed during initial tank cycling or when something may have died in the tank. This straightforward kit uses a two-part reagent with a 5-minute wait before comparing results to a color chart. Overall it is a decent and easy-to-use kit for occasional ammonia monitoring.

• 

  Salifert Calcium Test Kit

  This Salifert calcium kit is among the simplest to use: add 2ml of tank water, indicator powder, and 8 drops of reagent, then slowly titrate until the color changes. The whole process takes just a few minutes and the color change endpoint is clear and easy to identify. It is a reliable choice for routine reef tank calcium monitoring.

• 

  Salifert Carbonate Hardness & Alkalinity Test Kit

  This Salifert kit measures both Carbonate Hardness (dKH) and Alkalinity and is one of the simplest test kits to use. The process is quick: add 4ml of tank water, two drops of KH-Indicator, fill the syringe, then slowly add drops until the color changes. It is a reliable choice for routine alkalinity monitoring.

• 

  Salifert Iodine Test Kit

  This kit is not difficult to perform but several steps must be completed within seconds of each other, making it more stressful than other test kits. Reading the results is also tricky — the longer you wait to interpret the color, the darker it becomes, compounding the difficulty. Iodine is no longer tested or dosed in this system.

• 

  Salifert Magnesium Test Kit

  This kit gets the job done but the endpoint color change is not very distinct and the directions leave something to be desired. Magnesium testing becomes important when calcium levels are stubbornly low, since magnesium and calcium maintain a roughly 4:1 ratio — a target of around 1,450 ppm magnesium is maintained in this system. A LaMotte kit would be preferred but LaMotte does not make a straightforward magnesium test.

• 

  Salifert Nitrite Test Kit

  Nitrite testing is mainly needed during initial tank cycling; during normal operation it should always read undetectable. This kit uses a powder reagent with a 3-minute wait before comparing the color to a chart, making it one of the simpler Salifert kits to use. During healthy tank operation it can be performed very infrequently.

• 

  Salifert Phosphate Test Kit

  This test is simple to carry out — add tank water, one reagent, and a powder indicator — but interpreting the results is frustrating. The color chart gradations are so faint that distinguishing values below 0.5 ppm is nearly impossible. It works adequately for confirming very low or elevated phosphate, but is not reliable at trace levels.
