## Overview

Brightwell Aquatics Potassion-P is a premium, ultra-concentrated powdered potassium supplement designed specifically for reef aquariums, especially ultra-low-nutrient systems. It supports coral skeletal growth and enhances blue pigmentation in SPS corals by maintaining optimal potassium levels (390–410 ppm). Free from phosphates, silicates, and organics, this lab-grade formula delivers 6x the potassium strength of liquid alternatives, making it a cost-effective, scientifically formulated solution trusted by marine experts and reef enthusiasts alike.

## Description

Brightwell Aquatics Potassion-P is a high-purity powdered potassium supplement designed for reef aquariums, especially ultra-low-nutrient systems where potassium depletion can occur. Potassium plays a vital role in coral skeletal structure and is incorporated into pigments that enhance vivid blue coloration in small-polyp stony (SPS) corals. In natural seawater, potassium occurs at ~399 ppm and must be maintained between 390–410 ppm in reef systems for optimal coral growth and color. Potassion-P delivers exceptional purity and concentration, with each gram offering significantly more potassium than liquid products. This makes it a cost-effective choice for hobbyists managing multiple reef tanks or high-demand coral systems. Regular use supports the development of healthy skeletal structures and helps improve pigmentation, especially when paired with adequate iron levels. This supplement is free from unwanted additives like EDTA or gluconates and contains no phosphate, silicate, or organic content. Each batch is precision-formulated based on real-world aquarium data and marine science research. For best results, test potassium levels regularly and dose consistently to maintain a stable reef environment.

Does the job well. Much more economical for a large system, but can very well be used for any size system. Now that I am checking K, I didn’t realize how much it is consumed! Wow You will see a difference in your sps (coral) growth! Always use it with checking the L, never dose blindly. ( Salifert has a good reliable quality test kits)
