Mitsuru Aquarium Fe Test – water test strips

This Yokuchi Mitsuru Aquarium Test Fe is a drop-based kit for checking iron levels in aquarium water. It is aimed at keepers of planted tanks, competition aquariums and systems where iron fertilizers are added on a regular schedule, so that micronutrient dosing can be adjusted based on measured values rather than guesswork.

Why it matters

• Iron is a micronutrient that aquatic plants need for healthy growth, leaf colouration and overall condition.
• Regular Fe measurements help match micronutrient dosing to what the plants actually use.
• Monitoring allows deficiencies to be spotted early, before they show up in plant appearance.
• Tracking iron also helps avoid excessive accumulation of iron in the water when fertilizers are dosed frequently.

What it works with

The kit fits planted freshwater aquariums and competition tanks, where iron is part of the regular fertilization routine. It is most useful alongside a fertilizer program that contains iron, as the test results show whether the current dosing matches the water's actual iron content.
