accurate measurement of Dissolved Silica - for marine aquariums & tap water

• 2 x 25 ml, 1 x 10 ml

3 x reagent 3 for the sera magnesium Test

• 3 x 15 ml

The sera nitrite-Test makes it easy to determine the level of toxic nitrite.

• For approx. 75 measurements in fresh and salt water.

The Sera nitrite-test: Use during regular maintance to check the nitrite level in fresh-and saltwater aquariums and garden ponds. (...)

Fertilization according to the requirements of the plants is only possible if the iron level is monitored.

• For approx. 75 measurements

Compare the test results with the supplied color chart to obtain the iron level. (...)

For regularly checking the nitrate level in aquarium water.

• ca. 60 Tests
• Detect unwanted nitrate-simply,quickly and reliably by means of the sera-Test.
• Nitrate levels exceeding 50mg/l (ppM) promotes heavy algae growth and also sunts the growth of fish and plants. (...)

This test monitors the calcium level easily and precisely in steps of 20 mg/l (ppm).

• ca. 7.500 mg Ca
• The calcium level in saltwater can easily and safely be determined by using the sera calcium-Test.
• If the level falls below 400 mg/l (ppm), the calcium concentration can be increased with sera calcium plus. (...)

Makes it easy to monitor the carbonate hardness in fresh and salt water.

• ca. 420° dKH

Carbonate hardness (KH) stabilizes the pH value. (...)

Makes it easy to monitor the pH value in fresh and salt water and ponds.

• For approx. 100 measurements.

To achieve a stable pH value, ensure to maintain the carbonate hardness of at least 4°dKH. (...)

For approx. 60 measurements.

• Phosphate strongly promotes algae growth.
• Thus, it should be regularly checked by means of the sera phosphate-Test and be removed in freshwater with sera phosvec.
• The phosphate level should be below 1 mg/l (ppm) in freshwater resp. 0.1 mg/l (ppm) in saltwater. (...)

For monitoring chlorine in aquarium water.

• Chlorine is rapidly removed by sera chlorvec.

The sera chlorine-Test tells you whether the chlorine level is dangerous by simply comparing colors. (...)

tells you the overall concentration of ammonium and ammonia.

• The actual concentration of toxic free ammonia is easy to calculate from the measured level and the pH value by means of the enclosed calculation chart.
• sera bio nitrivec (freshwater) resp. sera ammovec (saltwater) break down ammonium and ammonia.
• ca. 60 tests (...)

60-second test for fresh water and sea water aquaria
