The source of nitrogen utilized in FlorinGro is derived from nitrate compounds. While plants unquestionably make use of ammonium and the constituents of urea very effectively, our experience and extensive research dictate that these compounds be excluded from FlorinGro as a result of the clear danger they pose to fishes and other non-plant aquarium inhabitants when aquarium pH is greater than 7.0; we feel that these nitrogen sources are useful to aquatic botanists and horticulturists, but that they are not suited to use in an aquarium. Nitrogen should primarily be present as nitrate and maintained at a concentration of less than 20 ppm. In addition to nitrogen, magnesium, iron, and potassium are important to chlorophyll production. Maintaining a total iron concentration of 0.05 - 0.10 ppm, magnesium concentration of ~5 ppm, and potassium concentration of 15 - 30 ppm, is recommended.
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. Maintain the nitrate concentration within a range of 10 - 20 ppm; it is not recommended to exceed 25 ppm nitrate in planted aquaria housing fishes and invertebrates.
Basic: Add 5 ml (1 capful) of product per 50 US-gallons (189.3 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 (9,464 L).
Advanced: Determine the nitrate concentration (“[NO3-]”) in the aquarium using an accurate test kit before supplementing. Each ml of FlorinGro will increase the [NO3-] in 1 US-gallon (3.785 L) of water by 17.5 ppm. Each drop (250- and 500-ml cap) will increase the [NO3-] in 1 US-gallon (3.785 L) of water by 2.2 ppm, and the [NO3-] in 20 US-gallons (75.7 L) by 0.11 ppm. If the initial [NO3-] in the aquarium is below 20 ppm, add this product at the maximum rate of 1 ml per 5 US-gallons daily until the desired concentration is attained, then dose daily or weekly as needed (see below). Always attempt to maintain the [NO3-] within a range of +/-2 ppm. To determine the dosing rate of this product once the desired [NO3-] has been acquired, measure the daily rate of nitrate uptake (i.e. the decrease in nitrate) in your aquarium by measuring the aquarium's [NO3-] at the same time each day over a one- to two-week period. To determine the daily dosing rate (preferable to weekly dosing) for nitrate maintenance: estimate the volume of water in the entire aquarium system; divide the daily decrease in [NO3-] by 17.5; multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable [NO3-]. Daily dosing maintains a more stable [NO3-] (and more natural environment) than dosing weekly, in which the [NO3-] spikes just after dosing and then gradually decreases throughout the course of the week. Heavily-planted aquaria with intense lighting, CO2 supplementation, and low- to moderate-stocking density of fish are likely to see the most dramatic results from nitrogen supplementation. Start at a low dosage and increase it as required, but do not overdose regardless of the temptation to do so.
