Water Test KitsUsing test kits to detect problematic water conditions is key to the sustainability of a healthy aquarium. For a fish-only tank, you should measure and monitor pH, alkalinity, ammonia, nitrite, and nitrate levels. In addition to these, you should also monitor the calcium, magnesium and strontium levels in a reef aquarium.
For the determination of the pH- value in seawater. Many organisms show an extremely sensitive reaction to fluctuations of the pH-value. With this test, the pH-value can be determined fast and accurately...ONLY$11.71
For the determination of the carbonate hardness or the alkalinity in seawater. The carbonate hardness or alkalinity corresponds to the buffer capacity of the aquarium water and therefore determines the stability of the pH...ONLY$10.09
