Nutrafin’s Iron Test (0.0 - 1.0 mg/L) measures iron levels in fresh and saltwater aquariums. Iron must be carefully monitored and kept at a level that supports and maintains lush, planted aquariums. It is recommended to test iron with a frequency that will maintain the suggested iron level of 0.25 to 0.5 mg/L. Show more
