Coral Shop Organics Test Kit
for saltwater or freshwater aquariums

Test is intended for the determination of dissolved organic matter (DOM) in seawater, as well as freshwater.

It is based on the reaction of sample with strong oxidizing agent, reacting not only with DOM but in less extent also with POM (Particulate Organic Matter) and some trace elements. Thus, formally we are talking about the test kit for determination of reducing matter in aqueous solutions. The results are expressed as the consumption of oxidizing agent in millimols per 1 litre of tested water.

Since the test kit is intended for general reefkeeping public, it was necessary to avoid the use of any concentrated acids and aggressive catalysers in test agents as well as a need of sample solution heating before titration. Because the oxidation of high-molecular organic compounds is relatively slow process, the only chance was to extend the reaction time of oxidizing agent with the sample without the access of air – in case of CS TEST Organics on 24 hours in closed titration flask or titration container respectively.
