JBL ProAqua Test Easy 7in1 quickly and simply identifies the 7 most important water measurements in the aquarium and garden pond as an orientation guide. The nitrate (NO³) and nitrite (NO²) values indicate whether the biological cleaning processes are functioning efficiently. CH (KH) is important to stabilise the pH level.
