Brightwell Chaeto GRO Macroalgae Nutrient Supplement for Reef Refugiums (500ml)

$40.00

Chaeto GRO is a specialized macroalgae nutrient supplement formulated to support the healthy growth and vigor of Chaetomorpha in marine aquariums and refugium systems. It provides a balanced blend of essential trace elements required for long-term algae health while remaining completely free of nitrate and phosphate.

Healthy Chaetomorpha macroalgae plays an important role in reef aquariums by naturally removing excess nutrients such as nitrate and phosphate through biological uptake. By supplying critical elements including iron, potassium, cobalt, molybdenum and other micronutrients, Chaeto GRO helps macroalgae grow more efficiently and maintain strong nutrient export capacity.

Chaeto GRO is particularly useful in ultra-low nutrient reef systems where trace elements may become depleted over time. Regular dosing helps maintain stable water chemistry and supports refugium performance without introducing unwanted nutrients.
