Tropic Marin® Potassium is a highly concentrated, premium supplement designed to restore potassium levels in marine reef aquariums to their natural seawater value of 408 ppm. Potassium is an essential macronutrient for all marine organisms, playing a critical role in skeletal calcification, soft tissue hydration, and enzyme production. While potassium consumption is generally low, the aggressive use of zeolites, activated carbon, and specialized nutrient adsorbers can strip potassium from your water. Depleted potassium levels manifest as stunted growth, dull gray colors, and retracted polyps on SPS corals. Supplementing with Tropic Marin Potassium safely rebuilds this macronutrient, delivering a massive vitality boost and restoring brilliant pink, red, and blue coloration.
Key benefits
Essential Coral Macronutrient: Restores the biological potassium levels needed for cellular regulation and skeletal growth.
Intensifies Coral Coloration: Specifically enhances the blues, reds, and pinks in SPS corals like Acropora, Montipora, and Stylophora.
Reverses Deficiency Symptoms: Treats stunted coral growth, weak tissue, and poor polyp expansion caused by nutrient carbon-adsorbers.
High Concentration Formula: Highly concentrated at 100 mg/ml potassium, meaning a small dose treats large volumes of water.
Extremely Safe and Purified: Free of unwanted phosphates, nitrates, and organic pollutants to keep your display tank pristine.
Specifications
Net volume: 500 ml (16.9 fl oz)
Form: Liquid mineral concentrate
Primary purpose: Potassium replenishment and coral color enhancement
Water type: Saltwater (Reef systems)
Intended users: Advanced reef keepers, coral collectors, and SPS specialists
Suggested use
Dosing Rate: A dose of 10 ml of Tropic Marin Potassium per 100 Liters (approx. 26 US gallons) increases the potassium concentration in the water by 10 mg/L (ppm). Alternatively, 15 ml raises potassium in 40 gallons by ~10 ppm.
Maximum Daily Dose: Do not exceed a maximum dosage of 20 ml per 100 Liters (26 gallons) of system water per day.
Measurement: Always test potassium levels using a professional test kit (like Tropic Marin K+ Test Pro) before dosing.
Ingredients Purified water, high-purity potassium salts.
Guaranteed Analysis
Potassium (K): 100,000 ppm (100 mg/ml).
Storage and safety
Store in a cool, dark place away from direct sunlight.
Keep the bottle tightly capped when not in use.
Keep out of reach of children and household pets.
Warnings
Do not exceed natural levels: Potassium levels should not be raised past natural seawater concentrations (~408 ppm), as excess potassium is harmful to sensitive invertebrates.
For aquarium use only. Not for human consumption.
What’s included
1 x Bottle of Tropic Marin Potassium Supplement (500 ml)
Why choose Tropic Marin Potassium is the safest, most precise way to restore depleted potassium in highly filtered reef tanks. If you are running ultra-low nutrient methods (ULNS) or heavy carbon filtration and are noticing your SPS corals losing their red and blue pigments, this high-purity liquid supplement is the perfect remedy to restore their natural, wild colors and robust growth.
