This test monitors the calcium level easily and precisely in steps of 20 mg/l (ppm) For approx. 7.500 mg (ppm) calcium. Add sera marin COMPONENT 1 Ca in case of too low Ca levels. A partial water change will help in case of too high levels.

Makes it easy to monitor the copper level in fresh and marine water Copper (Cu) is very toxic especially for invertebrates such as shrimps and crustaceans, but fish also react very sensitively to elevated copper levels. There are many possible causes for copper enrichment, including medical or algae combating treatments. The sera Cu-Test allows checking quickly whether fish or invertebrates are safe. sera aquatan provides help in case of elevated copper levels. Sufficient for approx. 50 measurements.

AMMONIUM TESTING METHOD  1. Take 3 ml of water sample in the test tube.  2. Add 4 drops of ammonium reagent - 1(NH-1) and mix well, The colour that forms is compared with ammonium colour chart immediately and record the ammonium value

Makes it easy to monitor the chlorine level in fresh and marine water Chlorine is immediately removed by sera toxivec or sera pond toxivec. sera aquatan or sera KOI PROTECT make the water fish friendly. Sufficient for approx. 45 measurements.
