First, a little background… I'm a relatively new fish pet owner. I have:

-2.5 gallon tank for my betta fish
-My betta has lived there for a year
-Tank has all bells and whistles (heater, decorations, etc.)

After a year of diligently providing food and cycling water, my betta started to become lethargic and eventually started biting his tail. The situation got worse when he got (possibly) fungal infection as his tail and fins started receding. I treated him with aquarium salt baths and out of desperation, treated him with Bettafix (with half the recommended dose), but he did not show any recovery.

I realized my inexperience as a new hobbyist, so I started to research and stumbled upon a fish care forum, in which one of the posters recommended Tetra Blackwater Extract as "therapy" for "stressed" fish or for promoting health for healthy fish. The advice made sense since freshwater fish needs more than water conditioner to neutralize chlorine, chloramines, and heavy metals, it also needs healthful bacteria and vitamins.

I'm happy to report that not only Tetra Blackwater Extract helped my betta to recover but it promoted healthful conditions for my fish to thrive. He now has his tail and fins grown back almost as long as before.

For healthful bacteria, I recommend Tetra SafeStart which I used simultaneously with Blackwater Extract. I hope Amazon will continue to carry these two great products from Tetra.

I've been using this peat extract for almost twenty years and even though they have changed the bottle, it is still the same, very great product!

Back in the day, I bred Angels and Discus. No water change was complete without a healthy dose of Tetra's Blackwater Extract. It softens the water better than a peat filter, it lowers the pH better than harmful chemicals, and the vitamins truly do trigger a response from the fish.

I now only have a Tetra tank with a few Corys to do the "dirty" work. After using this product with each water change, the Corys have started to breed and reproduce.

I get consistent pH and hardness readings, (with city water!!!), and the darkening of the water gives the tank a very natural "Amazon" feel. Even the Amazonian River plants seem to thrive better when I use this.

So cool to find it here for so much less than trying to buy it locally. If I can find it here in Minneapolis, the dudes want thirteen bucks a bottle, plus tax!

Never again! I'll buy it from Amazon each and every time!

I run mostly a tetra fish tank and this replicates the Amazon water conditions. Tetra is German, I've used their products since the 70's and highly recommend this and all their products.

This extract gives my tank that tea colored Amazonian look. My neon tetras grew like crazy and had great colors.

LOVE this stuff. My two oscars and my severum race toward the cloud of it and puff it in eagerly when they see it dump into the water...makes them instantly energetic and hungry. Also really seems to encourage and speed up healing.

Ever since i started using this product in my discus tanks my rasboras and rams have started to breed non stop. The discus look more healthy and lively along with giving it a really natural look.

I first used this product back in the 70's when it was called Blackwater Tonic. My fish love the "natural" environment it creates in the tank.
