The appropriate level of potassium is less than 30 milligrams per liter. Potassium deficiency is not immediately noticeable; initially, only the growth rate decreases, and as the deficiency continues, symptoms such as yellowing of older leaves, necrosis, and pinhole damage on the leaves can be observed. Eventually, these signs can also be seen in weakened stems and roots of the plants. High levels of potassium, which exceed the acceptable range, can disrupt the absorption of other elements. Deep Ocean Potassium Fertilizer can easily and safely raise potassium concentration and completely eliminate the symptoms of potassium deficiency.
* Made from USP-grade materials.
* The most specialized potassium fertilizer for plant growth, color, and health.
* Formulated with a similar percentage that is found and readily absorbable by plants.
* Exceptional rapid effectiveness and visible absorption.
* High concentration and cost-effective for large-volume planted aquariums.
* Safe for invertebrates like shrimp.
* This product is free of any nitrates and phosphates, allowing it to be used in conjunction with nitrogen and Deep Ocean phosphate for optimal results.
Basic Usage Instructions:
Before use, shake the bottle well and then add one cap (5 cc) for every 125 liters of aquarium water two to three times a week, or as needed based on the signs of potassium deficiency mentioned above.
Professional Usage Instructions:
Before use, measure the potassium level in the aquarium water using the Deep Ocean potassium test kit.
Reference 1: Each cc of Deep Ocean potassium fertilizer can increase potassium ion concentration by 5 ppm in 10 liters.
Reference 2: 5 cc of Deep Ocean potassium fertilizer can increase potassium ion concentration by 1.25 ppm in 200 liters.
Note1: The provided usage instructions and weekly fertilization schedule represent a general method and average consumption for all planted aquariums. The volume and needs of the plants, as well as the types of aquatic organisms in each aquarium, may vary. Therefore, to achieve the best condition for the plants, the amount of fertilization should correspond to the volume and needs of the planted species in the aquarium. The aquarium manager should adjust the fertilizer dosage based on the growth status, color of the plants, and their visible symptoms. It is evident that excessive fertilization can lead to algae growth, while insufficient fertilization can result in reduced color and growth.
Note2: In the colder months, crystals may occasionally form at the bottom of the potassium bottle over time. This is normal and occurs due to the very high concentration of the product (50,000 mg per liter of dissolved potassium) and happens when the storage location is consistently kept at a low temperature (below 20 degrees Celsius) without movement. In this case, if it is kept for a few days at a suitable room temperature (around 25 degrees), the crystals will dissolve back into the bottle. Alternatively, if necessary, the bottle can be warmed by placing it in warm (not hot) water for a few minutes to raise the temperature and dissolve the crystals easily.
