Brightwell Aquatics Ferrion

Instructions and Guidelines

Basic: Shake product well before using. Add 5 ml (1 capful) of product per 50 US-gallons of aquarium water every other day or as needed to maintain the iron concentration within a range of 0.05 – 0.10 ppm. When used in this fashion, 250 ml treats up to 2,500 US-gallons (9,464 L).

Advanced: Determine the iron concentration in the aquarium using an accurate test kit before supplementing. Shake this product well before using. Each ml of Ferrion will increase the concentration of iron (“[Fe3+]”) in 1 US-gallon (3.785 L) of water by 1 ppm. It is advisable to ensure that the concentration of phosphate not exceed 0.05 ppm in the aquarium to be dosed with an iron supplement; see opposite sidebar for additional information. If the initial [Fe3+] in the aquarium is below 0.10 ppm, add this product at the maximum rate of 10 ml per 20 US-gallons daily until the desired concentration is attained, then dose daily or weekly as needed (see below). Always attempt to maintain the [Fe3+] within a range of +/-0.02 ppm. To determine the dosing rate of this product once the desired [Fe3+] has been acquired, measure the daily rate of iron uptake (i.e. the decrease in iron) in your aquarium by measuring the aquarium’s [Fe3+] at the same time each day over a one- to two-week period. To determine the daily dosing rate (preferable to weekly dosing) for iron maintenance: estimate the volume of water in the entire aquarium system; multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable [Fe3+]. Daily dosing maintains a more stable [Fe3+] (and more natural environment) than dosing weekly, in which the [Fe3+] spikes just after dosing and then gradually decreases throughout the course of the week.

Caution: Keep out of reach of children. Not for human consumption.
