Water Test Kits

Using 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.
