ReeFlowers Pure Potassium is of high purity and contains a minimum of 500,000 ppm of potassium per kilogram.Potassium is a key component of coral skeletons.
Its deficiency dulls colors and causes tissue loss. The pigments that create the purple and blue colors found in some polyps are important for regulating neurological functions and are consumed by living organisms in aquariums.
The potassium concentration found in natural sea water is approximately 400 ppm. The value in the aquariums should be close to this value.
The potassium consumption rate is different for each aquarium. Before using the product, measure the potassium concentration in the aquarium using a test kit. Add up to 1 gr per 100 lt until the potassium reaches the desired level. 1 gr Pure Potassium (1 ml Pure Potassium = ~1,4 gr) provides a 5 ppm increasing in 100 lt. When the required levels are reached, then periodic testing should be performed to find consumption amounts and the water should be topped-up as required on a daily or weekly basis. The suggested quantity should be dissolved in freshwater and added to the sump.
If not using a Potassium test, then it is recommended to use 0.5 g per 100 lt on a weekly basis for a tank with an average population density. For long term use, no more than 1 gr should be used per 100 lt on a weekly basis.
