Brightwell Aquaitcs Florin-Fe provides your planted aquaria with the iron supplement it needs.
Iron is an essential element for both aquatic and terrestrial plants because it aids in chlorophyll production. Also, in small concentrations, iron activates certain enzymes that take part in metabolic reactions. Iron is considered a micronutrient and is often the limiting element in plant production in some aquatic habitats.
Brightwell Aquatics Florin-Fe delivers iron in two steps - immediate and delayed - through natural biological and photochemical reactions taking place within all aquaria.
Shake product well before using. The most effective method of using any ion-specific supplement is to determine the ionic concentration in the aquarium prior to supplementing.
Basic: Add 5 ml (1 capful) of product per 50 US-gallons (187.3 L) of aquarium water every other day or as required; this corresponds to 1 ml (~8 drops) per 10 US-gallons (37.9 L). When used in this fashion, 250 ml treats up to 2,500 US-gallons (9,463.5 L). Maintain the iron concentration within a range of 0.05 - 0.10 ppm.
Advanced: Determine the iron concentration in the aquarium using an accurate test kit before supplementing. Each ml of Florin-Fe will increase the concentration of total iron (“[Fe2+/3+]”) in 1 US-gallon (3.785 L) of water by 3.2 ppm. Each drop (250- and 500-ml cap) will increase the [Fe2+/3+] in 1 US-gallon (3.785 L) of water by 0.4 ppm, and the [Fe2+/3+] in 20 US-gallons (75.7 L) by 0.02 ppm. Maintain the iron concentration within a range of 0.05 - 0.10 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. If the initial [Fe2+/3+] in the aquarium is below 0.05 ppm, add this product at the maximum rate of 1 ml per 10 US-gallons daily until the desired concentration is attained, then dose daily or weekly as needed (see below). Always attempt to maintain the [Fe2+/3+] within a range of +/-0.02 ppm. To determine the dosing rate of this product once the desired [Fe2+/3+] has been acquired, measure the daily rate of iron uptake (i.e. the decrease in iron) in your aquarium by measuring the aquarium's [Fe2+/3+] 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; divide the daily decrease in [Fe2+/3+] by 3.2; multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable [Fe2+/3+]. Daily dosing maintains a more stable [Fe2+/3+] (and more natural environment) than dosing weekly, in which the [Fe2+/3+] spikes just after dosing and then gradually decreases throughout the course of the week. See opposite panel for additional important information on this subject.
