Overview
- Highly-concentrated ionic calcium solution.
- Increases the concentration of calcium in marine aquarium water to provide corals and other reef-building invertebrates with one of the most important elements required for growth.
- Is ionic rather than chelated, and contains no unwanted organic material such as EDTA, gluconate, or polygluconate.
- Over 50% stronger than most competing products.
- Free of phosphate, silicate, and organic material.
- Formulated by a marine scientist.
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 calcium concentration within a range of 412 - 450 ppm. When used in this fashion, 250 ml treats up to 2,500 US-gallons (9,464 L).
Advanced: Determine the calcium concentration in the aquarium using an accurate test kit before supplementing. Shake this product well before each use. Each ml of Calcion will increase the concentration of calcium (“[Ca2+]”) in 1 US-gallon (3.785 L) of water by approximately 40 ppm. If the initial [Ca2+] in the aquarium is below 412 ppm, add this product at the maximum rate of 10 ml per 20 US-gallons daily until the desired calcium concentration is attained, then dose daily or weekly as needed (see below). Always try to maintain the [Ca2+] within a range of +/-10 ppm. To determine the dosing rate of this product once the desired [Ca2+] has been acquired, measure the daily rate of calcium uptake (i.e. the decrease in calcium) in your aquarium by measuring the [Ca2+] at the same time each day over a one- to two-week period. To determine the daily dosing rate (preferable to weekly dosing) for calcium maintenance: estimate the volume of water in the entire aquarium system; divide the daily decrease in [Ca2+] by 40; multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable [Ca2+]. Daily dosing maintains a more stable [Ca2+] (and more natural environment) than dosing weekly, in which the [Ca2+] 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.
