Description
Florin K
Technical Overview:
Potassium is one of the most important elements for plant growth and health;
it is utilized in photosynthesis, maintaining ion (charge) balance, in the
translocation of important organic and inorganic compounds (such as sugars
and nutrients, respectively), and it is essential to many of the biochemical
reactions taking place within plant tissues, as is evidenced by the relatively
high percentage of plant tissue that potassium accounts for (second only to
nitrogen). The affinity that a given species of plant shows for potassium
may be partially dependant upon that species’ tendency to flower and
form complex root systems (both of these correspond to greater potassium requirements
than in bunch plants or those that rarely flower, per unit mass). Environmental
factors such as light intensity and duration, and the presence of other nutrients
in adequate concentrations, may also influence potassium requirements.
Because potassium is utilized in photosynthesis, a deficiency can lead to
chlorosis, in which insufficient chlorophyll is produced and the leaves become
pale; if not remedied, the plant may suffer extensive tissue decay (chlorophyll
is utilized in the production of new tissue) and eventually perish. Chlorosis
is likely to appear first in the older leaves of the plant, which tend to
be on the periphery. In addition to potassium, magnesium, iron, and nitrogen
are important to chlorophyll production. Maintaining a total iron concentration
of 0.05 - 0.10 ppm, and magnesium concentration of ~5 ppm, is generally sufficient;
nitrogen should primarily be present as nitrate at a concentration of less
than 20 ppm. The required concentration of potassium may vary in mended to
begin by maintaining the concentration at approximately 15 ppm for the first
week and adjusting the concentration by 1 - 2 ppm every two weeks as the appearance
of the plants dictate; the recommended upper limit for potassium is approximately
30 ppm. The rate at which potassium is extracted from the water is largely
dependant upon the rate of plant growth, therefore densely-planted systems
with optimal chemical and environmental conditions are likely to require regular
potassium supplementation.
Brightwell Aquatics Florin-K is a high-purity potassium supplement, and is
free of chloride (while chloride is a vital element to plants, it is required
in a very small concentration, provided in Brightwell Aquatics FlorinMulti).
Because the potassium requirement of aquatic plants is high relative to that
of other nutrients, Florin-K is very strong (50,000 ppm), making it an effective
and economical potassium source.
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. Maintain the potassium concentration within a range of 15 -
30 ppm; 20 - 25 ppm is a more narrow range, and one that will likely be extremely
effective in most planted aquaria.
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 potassium concentration (“[K+]”) in the
aquarium using an accurate test kit before supplementing. Each ml of Florin-K
will increase the [K+] in 1 US-gallon (3.785 L) of water by 13.2 ppm. Each
drop (125-, 250-, and 500-ml cap) will increase the [K+] in 1 US-gallon (3.785
L) of water by 1.7 ppm, and the [K+] in 20 US-gallons (75.7 L) by 0.08 ppm.
If the initial [K+] in the aquarium is below 15 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 [K+] within a range of +/-2 ppm. To determine the dosing rate
of this product once the desired [K+] has been acquired, measure the daily
rate of potassium uptake (i.e. the decrease in potassium) in your aquarium
by measuring the aquarium's [K+] at the same time each day over a one- to
two-week period. To determine the daily dosing rate (preferable to weekly
dosing) for potassium maintenance: estimate the volume of water in the entire
aquarium system; divide the daily decrease in [K+] by 13.2; multiply this
number by the volume of water in the system to get the daily dosage required
(ml) to maintain a stable [K+]. Daily dosing maintains a more stable [K+]
(and more natural environment) than dosing weekly, in which the [K+] spikes
just after dosing and then gradually decreases throughout the course of the
week.
