Sale priceDhs. 99.00



  • Shrimp safe and copper free..
  • Establishes similar water conditions to those found in Blackwater rivers, many of which are home to important aquarium shrimp, fishes and plants without heavy darkening of the water..
  • Detoxifies copper and heavy metals..
  • May be used to help simulate the onset of the rainy season for encouragement of spawning..
  • Provides humic substances (humic and fulvic acid), complex bio-organic molecules known to increase the availability of important nutrients (such as iron, calcium, magnesium, molybdenum, manganese, zinc, cobalt, and nickel) to plants, potentially enhancing the effectiveness of plant nutrient solutions in aquaria..
  • Imported from USA.


Humic substances are natural derivatives of organic materials
found in soils and, more importantly (for aquarium hobbyists), in
many forested streams and rivers. They are collectively comprised
of humic and fulvic acids, which are the product of the natural
decomposition of proteins, carbohydrates, lipids, and lignins of
plant and/or animal origin. A characteristic of humic substances
is their deep brown color, which is responsible for the color of
soil. Soluble humic substances increase the bioavailability of
multivalent cations (many of which are important nutrients for
plants) to plants considerably by forming temporary bonds with
these ions and making their uptake by plants more direct; this
increases the effectiveness that water care products containing
these ions will have in planted aquaria. Gradually increasing the
concentration of humic substances in aquaria is an effective
method of encouraging spawning in fishes, particularly for
Discus, Cardinal Tetras, and other inhabitants of such blackwater
rivers as Brazil’s Rio Negro. In general, the concentration of
humic substances increases substantially during periods of
excessive precipitation and/or flooding (e.g. “rainy season”),
which is also when fishes in many river systems spawn. The
addition of Brightwell Aquatics Shrimp BlackWaterClear to an
aquarium will slightly acidify the water, and will discolor it
slightly in direct correlation with the dosage used, the volume
of the water in the entire aquarium system, and the method(s) of
chemical filtration employed; in general, the greater the dosage
employed, the more pronounced the change in water coloration will
be. Shrimp BlackWaterClear will also soften water as a result of
the natural chelating action of humic substances. These are all
important environmental and/or chemical cues utilized by fishes
for the onset of spawning.
