Two Little Fishies Potassium Concentrate – Reef-Safe Mineral Supplement for Coral Color & Growth (500 ml)

Two Little Fishies Potassium Concentrate is a professional reef supplement designed to restore potassium levels in marine aquariums. Potassium plays a vital role in cellular function and coral pigmentation, occurring naturally at around 400 mg/L in seawater.

As coral growth and filtration can strip potassium from tank water, this formula helps maintain ideal concentrations to prevent issues like color fading, slow skeletal growth, or tissue damage. Especially beneficial for SPS-dominant and low-nutrient reef systems.
