Brightwell Aquatics Florin-Fe Ferrous & Ferric Iron for Planted FW Aquaria, 500 ml
Features
- Provides both ferrous (Fe2+) and ferric (Fe3+) iron sources to maximize benefit to planted aquaria.
- Two-tiered approach to iron supplementation consists of one ingredient to deliver immediate iron and another ingredient that slowly releases iron during the light cycle,when the aquarium is illuminated.
- Over 50% stronger than most competing products.
- Formulated utilizing extensive research on aquatic plant nutrient requirements.
Instructions and Guidelines
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.
