The sera ammonium/ammonia-Test tells you the overall concentration of ammonium and ammonia.

This professional set consists of nine different water tests for aquarists and pond owners.

This professional set consists of eight different water tests for saltwater aquarists

Contains the most important water tests for fresh and saltwater:

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

REFILL for Sera Calcium Test Kit

For monitoring chlorine in aquarium water. Chlorine is rapidly removed by sera chlorvec

For permanently checking the CO2 level in aquarium water

For checking the copper level in tap water. Also for monitoring the application of copper containing additives. sera aquatan immediately binds copper.

Makes it easy to monitor the total hardness.

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

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

Makes it easy to monitor the magnesium level in saltwater aquariums.

3 x reagent 3 for the sera magnesium Test

For regularly checking the nitrate level in aquarium water.

The sera nitrite-Test makes it easy to determine the level of toxic nitrite. For approx. 75 measurements in fresh and salt water.

sera oxygen-Test (O2) displays possible dangerous situations within minutes.

Makes it easy to monitor the pH value in fresh and salt water and ponds. For approx. 100 measurements.

Phosphate strongly promotes algae growth. Thus, it should be regularly checked by means of the sera phosphate

This kit combines the Marine pH & Alkalinity, Ammonia and Nitrite & Nitrate kits into one kit.

Marine ph & Alkalinity features a unique dye that has a pronounced color change between 8.0 and 8.3, making it the easiest kit on the market to read in that critical range.

This kit measures nitrite down to 0.2 mg/L and nitrate down to 2 mg/L in marine or freshwater.

This kit measures inorganic phosphate down to 0.05 mg/L, producing a unique easy to read yellow-green-blue color range in marine and freshwater.

For the determination of the calcium concentration in saltwater.

For the determination of the phosphate concentration in fresh and seawater.

This kit measures total (NH3 and NH4+) and free ammonia (NH3 only) down to 0.05 mg/L and is virtually interference free in marine and fresh water.

This kit measures copper (all types) down to 0.01 mg/L in marine or freshwater. Uses a highly sensitive catalysis based procedure.

This kit measures iodine or iodide to less than 0.005 mg/L. Seachem stands alone in offering this important test to the reef aquarian.

This kit measures iron in freshwater or marine water to less than 0.05 mg/L. Can also measure chelated iron.

This kit combines the Phosphate, Silicate, and Iodine/Iodide kits into one kit.

This kit measures all types of calcium, including gluconate calcium. The method is based on specific titration with a unique indicator. Measures in increments of 5 mg/L. Each kit runs 150 tests.

Four kits in one! Tests for magnesium,carbonate alkalinity, borate alkalintiy and total alkalinity in 0.1 meq/L resolution through a titration based procedure.

This kit measures strontium by first seperating the strontium in the sample by a chemical precipitation and filtration, followed by a sensitive titration in 0.5 mg/L increments. Each kit runs 50 tests
