SALIFERT COPPER TEST KIT

The Salifert Copper (Cu) Test Kit is a highly accurate tool designed to detect free copper levels in marine and freshwater aquariums. Copper is commonly used in fish-only systems to treat parasites and infections, but even small overdoses can be lethal to fish and invertebrates.

This test kit is sensitive enough to measure copper levels as low as 0.05 ppm, helping aquarists dose medications precisely or ensure their tank is copper-free — especially critical for reef and invert systems. Easy to use and fast-acting, the Salifert Copper Test provides clear, color-coded results within minutes.

Whether you’re medicating fish or verifying water safety, this kit gives you the control and confidence you need to protect your livestock.
