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. Blackwater rivers are so-called because of the coloration of the water, which ranges from light- to dark-brown (as a result of the presence of humic substances), but is transparent. There are many important blackwater rivers in the and Orinoco River drainages, as well as throughout forested regions of Southeast Asia, all origins of many families of important aquarium fishes. Blackwater biotope aquaria are therefore desirable when attempting to maintain these fish. 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 BlackWater to an aquarium will slightly acidify the water, and will discolor it 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. BlackWater 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 fish for the onset of spawning.

I like the no tannin tint
I know most people want tannins for blackwater tanks, but in my case, I was looking for something to help lower ph and soften the water and bought it because reviews said it didn't tint the water. Yes, it does look greenish going in the tank but it dissipates quickly. So for me, this worked.

Don't know if it works
Breeding tetras proved hard for me. But I tried hard species to breed(not glowlight, black neon, or so). I can't say it doesn't work, but won't stain the water.

A great additive to routine water changes for tropical aquascape
This stuff seems to really bring out the urge in some of the fish. My Corydora Julii population has doubled since I included a few drops this stuff in my routine water changes. I'm not certain it's the main reason, but I've never seen them laying eggs up until then (I'm not an expert). The school of ember tetras I have with the corys also seem more vibrant and active. I live in an area where the water is a bit on the hard side (more alkaline), so anything that can help soften it to a level tropical fish can thrive in helps.

Not for the appearance of tinted water,
Great product, however a misleading branding. Don’t use if you are expecting an instant “black water” style tank. The products they make to simulate black water don’t actually tint the water enough to be used in that particular fashion. It should specify that it only simulates the water chemistry of black water. Basically, if you want “tinted black water” it’s quicker to just boil almond leaves and other botanicals!

Won’t turn tank water yellow; still, a good product
The label on this is misleading. I was looking for something to add tannins to my Betta tank, and turn the water dark yellow or brown. The label on this product leads one to believe this does that. However, I decided to try it, and I like the product.

Didn’t last 6 months before smelling rancid
This product is good but short shelf life, don’t buy this big container if you can’t finish it in a few months

Good in theory
I'm sure this product means well but I even used a double dose on my tank with this product and my water wasn't even stained the nice brown color you want for a black water tetra tank.

Useful for raising dart frog tadpoles
There are many ways to prepare water for rearing dendrobatid tadpoles; I've had success raising many tadpoles with this product as part of my husbandry regime.
