Questions & Answers

Can I use this water conditioner in a fish aquarium in the my house
Answer by ChewyAug 11, 2020
The API Pond Stress Coat is safe for all fish, including koi and goldfish, invertebrates, and plants.

Can this be used in aquariums also? Second question will this help with well water?
Answer by ChewyFeb 04, 2019
This may be used within an aquarium, if proper dosage is measured for a much smaller quantity. For aquariums we typically recommend the API Stress Coat Aquarium Water Conditioner, since much smaller amounts will be needed. This conditioner will help to remove chlorine, chloramines, and detoxify heavy metals.

Can you tell me how much of this product to use in a 750 gallon pond that is being cleaned out
Answer by ChewyAug 24, 2017
You'll add 1 tablespoon per 60 gallons of water to be treated, 4 tablespoons per 240 gallons to be treated, or ½ cup per 480 gallons to be treated.

Is it safe if my cats drink the pond water
Answer by ChewySep 18, 2021
While it is important to keep the bottles of concentrated product away from animals, once the product is diluted per the dosing instructions, it is then possible for any pets or wildlife to come and either swim or take a drink from the water. You do not need to keep pets and wildlife away from the water.

Use regularly

We’ve used this product since we built our pond six years ago. Our fish have been healthy. We use it when we clean weekly or after any heavy rainfall. Works great!

Great product!

Seems to help a lot with creating a slime coat for the fish, especially if they have any wounds. It helps heal them and recover from any injuries.

Stress Coat works

I use Stress Coat whenever I have to drain water from my pond and add fresh water. It take the chlorine out and provides a healthy coat for my Koi. I've used it for years and have never had any problems with my fish. Recommend highly for ponds with fish.
