## Overview

Brightwell Aquatics Blackwater Humic Fulvic Acid Supplement is a 2L liquid formula designed to replicate natural blackwater river conditions. It enhances nutrient bioavailability for freshwater plants, supports stable water parameters, and encourages natural spawning behaviors in softwater fish species. Made in the USA, this premium supplement is essential for planted tanks and biotope aquariums seeking vibrant growth and healthier aquatic life.

## Description

Brightwell Aquatics BlackWater is a premium humic substance supplement formulated to replicate the natural conditions found in blackwater river systems such as the desertcart, Rio Negro, and forested Southeast Asian streams. Rich in humic and fulvic acids, BlackWater not only darkens the water slightly to create a more natural habitat, but also enhances the bioavailability of critical nutrients for aquatic plants, like iron, calcium, magnesium, and trace elements. This helps maximize the effectiveness of plant nutrient dosing and promotes lush growth in planted aquariums. BlackWater is especially beneficial for freshwater fish and shrimp species that come from low-mineral environments, such as Discus, Tetras, and other softwater fish. By naturally softening water and creating environmental cues tied to the rainy season, it can also help stimulate breeding behavior. When used regularly, BlackWater supports stable conditions, improved coloration, reduced stress, and better overall vitality for your aquatic life. Whether you're building a blackwater biotope, maintaining a planted tank, or encouraging fish to spawn, Brightwell BlackWater is an essential part of your freshwater aquarium care routine.

Review: Works well. Also seems to initiate spawning as I had eggs in the tank a few days after adding.
Review: Every time I use this my fish seem happy and breed
