  • Good value
Size: 1-Gallon Style: Aquarium Treatment
This product conditioned my water well. It was good value for the money.

  • A Must Have & It Works Great!
Size: 4-Ounce Style: Aquarium Treatment
I had a very stressed out blood parrot after moving him into a different aquarium. The water parameters were all normal so I knew it was due to stress from moving him and not from the water quality. Blood parrot cichlids don't like being moved, they're very territorial of their tanks and moving them tends to stress them out which causes the black discoloration. After just two doses of API Stress Coat combined with API Stress Zyme he's back to his normal color in one week's time! It works! Lowers stress in fish by 40%. Great to add to the aquarium when doing water changes, adding new fish, or just anytime. Also has aloe vera to coat damaged scales, fins, and tissue to aid in the healing process of injured fish or damage caused by tail biters. This is a must have in the aquarium world and I use it regularly! Works great! Highly recommend! ... show more

  • Necessary for Healthy Fish
Size: 32-Ounce Style: Aquarium Treatment
If you have an aquarium of any size and are using a water conditioner only, you need to purchase this now! It keeps my fish so healthy and their coats are beautiful!!! Protects them from ick, fungus and so much more! My fish in the photos are all several years old. The two huge goldfish were won at a fair 5 YEARS AGO. They're all thriving. ... show more

  • Great water conditioner and good for plants also!
Size: 1-Gallon Style: Aquarium Treatment
I have been using this aquarium water conditioner for a few years in my cherry shrimp, dwarf Mexican crayfish, and nano fish tanks. One drop goes a long way to dechlorinate a gallon of water. The gallon will last a long time. After watching a YouTuber who uses this for his plant water I decided to try it myself. Time will tell if it actually improves the health of my many house plants. This is a name brand and high quality product. I highly recommend it. ... show more

  • Works great, but not safe for axolotls
Size: 32-Ounce Style: Aquarium Treatment
Its actually a wonderful product, and works well. I'm mainly writing this review to let others know this product is not axolotl safe. I'm a beginner and was reccomended this by another axolotl owner. This product damages axolotl slime coat. It is my own fault, and I should have done more research. That being said, the product definitely did it's job and lowered ph quite easily. ... show more

  • Always works great
Size: 4-Ounce Style: Aquarium Treatment
I use this stress coat brand every time! It definitely helps my fish when I change their water and clean their tank. This is a great value for the price as it’s usually fairly expensive.

I like it because when I read reviews it said that this was good for your plants as well so I put a couple of drops in the water and I water my plants and they look good
