Product Description

API Pond Stress Coat instantly makes tap water safe for fish, removes chlorine, chloramines and toxic ammonia, reduces stress and adds a protective slime coat for enhanced disease prevention. Use during start-up and regular water changes to help keep your fish healthy and your pond water safe.

  • Removes chlorine, chloramines and ammonia
  • Detoxifies heavy metals from tap water
  • Replenishes fish slime coat, reduces stress and heals wounds

Stress Coat completely neutralizes and removes chlorine, chloramines and ammonia and detoxifies heavy metals to make water from the hose safe for pond fish. It replenishes the natural protective slime coat, making fish less susceptible to disease during times of high stress. Stress Coat is made with Aloe Vera, which promotes healing and helps restore damaged skin, fins and other fish wounds. Use whenever adding tap water or fish to the pond or when fish are injured.

Made in the USA.

Directions: When adding water to the pond: add 4 Tbsp. per 240 gallons of pond water, or 1/2 cup for each 48- gallons. In areas of known high chloramine use by local water companies, double the dose for added fish protection. When introducing fish to the pond or to promote healing: double the dose. 16 oz treats up to 1,920 gallons. 32 oz treats up to 3,840 gallons. 64 oz treats up to 7,680 gallons. 1 gallon treats up to 15,360 gallons.

Note: Formerly known as Pondcare Stress Coat Plus.

As always outstanding!

As always outstanding! Arrives quickly, no problems and it is always exactly what I needed and I don't have to go searching all the pet stores, aquatics stores for what I need for my Koi pond! Thank you!

Great product!

Not only great for fish, but safe for all my other animals to drink....I won't ever use chemicals as long as this is available

Great product

Not only does this product help build slim coat and help condition the water but it also helps clear the water. This hot year my pond has been awfully murky, but once I add the stress coat it's crystal clear.

Great product for fish

I started using this product after my fish were distressed or getting sores on their bodies. Part of the cause may have been from adding tap water to the pond. I tried Stress Coat each time I added water to the pond or when I added Algae Fix. Since then, all my fish have continued to thrive without suffering from sores. I highly recommend this product to care for you fish.

Awesome Product!

This is the best stuff I have ever used. I raise Koi inside in aquariums and then move them to the pond for sale. The fish love it and it keeps their slime coat and keeps them happy during water changes. I swear by this product when you use it in combination with the correct amount of Pond Salt!

Pond Care has great products

I have had my pond for 4 years and for the last 2 years have used the Pond Care product line with wonderful results.

Tom, Clio MI on 08-10-2007
Works Great

I found that Pondcare Stress Coat works great in all of my Cichlid Tanks, and is a lot cheaper. I have never lost a fish at a water change since I started using Pondcare.

Patrick, Los Angeles CA on 07-09-2007
Stress Coat

Pondcare StressCoat seems to work just fine. Doesn't seem to harm the fish....
