SERA Iron Test — Iron Test Kit for Aquariums

SERA Iron Test is a precise and easy-to-use colorimetric test kit designed to measure the concentration of available iron in freshwater and saltwater aquarium water. This test helps prevent iron deficiencies or excesses that affect the health of aquatic plants, algae growth, and the overall quality of the aquatic ecosystem.

Product summary

SERA Iron Test Kit — fast and reliable measurement of available iron (Fe) in water, measuring range adapted to the needs of aquatic plants, results visible in minutes. Contents: reagents, syringe/dropper, colorimetric comparison tube and instructions for use in French.

Main features

• Measurement: Available iron (Fe) in water, in mg/L (ppm). Measurement range: Accurate reading for low concentrations, suitable for planted aquariums. Fast result: Visual reading in minutes. Kit contents: Required reagents, graduated syringe or pipette, colorimetric tube or comparator, instructions. Use: Freshwater and saltwater (check instructions for each use).

Benefits

• Allows you to adjust the trace element levels for plants to prevent yellowing leaves and stunted growth. Helps diagnose the causes of slow growth or plant decline. Simple to use, suitable for beginners and experienced aquarists alike. An economical kit for regular aquarium maintenance testing.

Instructions for use (summary)

1. Collect the water sample according to the instructions. Add the specified number of drops of reagent A followed by B (or other sequence as per the instructions) to the sample tube. Gently shake and wait the indicated time (usually a few minutes). Compare the resulting color to the provided scale to read the concentration in mg/L (ppm).

Usage tips

Perform the test at room temperature and away from direct light to avoid any color alteration. Adhere to the indicated volumes and waiting times. For accurate measurements, rinse the tube between each test and use distilled water for the reference scale if necessary.

Measured parameters and interpretation

The test measures bioavailable iron (Fe) in mg/L (ppm). Values that are too low can cause chlorosis (yellowing) on young plant leaves; values that are too high promote algae growth and can harm some invertebrates. Interpret the results according to the type of tank: planted aquariums generally require low, regular applications (e.g., 0.1–0.5 mg/L depending on the species), while some specific systems may require different ranges—refer to the recommendations of fertilizer and plant suppliers.

Box contents

• Bottles of reagents A and B (quantities vary depending on the kit version). Sampling tube(s) and/or colorimetric comparator. Pipette or graduated syringe for sampling. Instructions for use in French.

Precautions and safety

Do not ingest the reagents; keep out of reach of children and animals. Avoid prolonged contact with skin or eyes; if contact occurs, rinse thoroughly with clean water and consult a doctor if necessary. Do not dispose of the reagents in the environment; dispose of in accordance with local regulations.

Compatibility and preservation

Compatible with most freshwater and saltwater aquariums — check the instructions for any restrictions. Store reagents in a cool, dry, dark place, tightly closed; observe the expiration date.

Technical notes and recommendations

For reliable monitoring, perform regular tests (weekly or according to a maintenance protocol) and record the results to detect trends. If you are using a complete fertilizer, adjust the iron content according to the measured values and the specific needs of the plants present. If in doubt (abnormal values or marked symptoms on the plants), perform a control test with a second kit or contact an aquarium specialist.
