About this product
This 20 L jug of blackwater aquarium water treatment from Brightwell Aquatics is a liquid that contains humic and fulvic acids. It is formulated for freshwater aquariums, where it slightly darkens the water to replicate blackwater river conditions. The container holds 20 L and weighs 19.28 kg (42.5 lb).
Humic and fulvic acids in the formula
Humic acid and fulvic acid are the two ingredients named for this treatment. Both are listed as part of the formula, and the liquid itself is clear in colour before it goes into the tank.
The product carries the model number BWR20L. It is sold as a liquid rather than a powder or tablet, and its stated use is as a coat.
Which tanks it is made for
The treatment is formulated for freshwater aquariums, so it does not suit saltwater or reef systems. Buyers should also be ready for the colour change: the liquid slightly darkens the water to replicate blackwater river conditions, which tints the view into the tank.
At 20 L and 19.28 kg (42.5 lb), the container is a large one. Measure out what the tank needs rather than pouring from the jug, and check that you have somewhere to store a container of that weight.

What the acids do in the water
The humic and fulvic acids are the components behind the product's stated effect on appearance. When added to a freshwater tank, the liquid slightly darkens the water so it resembles blackwater river conditions.
Because the liquid is clear in the container, the darkening happens once it is in the aquarium water, not before. The product is aimed at fish as its target audience.
