Best product ever

lostout2010 July 23, 2016

I have had fish for many years and stress coat is the best water conditioner I have ever used. If I have a fish the is not doing to good pouring a little stress coat helps sometimes. I won't use anything else.

API Stress Coat+ helped keep my fish calm and acti

AlinaK April 10, 2026

[This review was collected as part of a promotion.] To test the product, I completely cleaned out the aquarium, right down to the pebbles. This meant that the entire microbial ecosystem had to start rebuilding from scratch, which is always a stressful process for the fish, so it’s crucial to maintain as much environmental stability as possible. I used API Stress Coat+ and really saw a difference. The fish remained active, wasn’t scared by the changes, adapted quickly, and behaved as usual. For me, this is a huge plus, because after a complete aquarium clean, I’m always about the fish’s stress levels. This time everything went much more smoothly 🐠

Makes life easier!

AileenG April 27, 2026

[This review was collected as part of a promotion.] Using Stress coat has been a game changer. Very easy simple to use and haven’t needed as many water changes as usual. Water looks great, fish are thriving and no need to upkeep as much. Returning customer forsure!

API Stress Coat - A Must Have

RachelP April 14, 2026

[This review was collected as part of a promotion.] I was able to use API's Stress Coat for aquariums for free and provide my feedback. I find this product extremely useful for my fish tanks. I have 3 fish tanks and use this whenever I do a water change or clean the tanks. The product is designed to remove chlorine, Chlorimides and heavy metals to help make the water safe and livable for my fish. It also contains aloe Vera which promotes healing if they are hurt or ill. It helps generate new fish tissue and create a barrier/slime coat to prevent electrolyte loss. I use this whenever I clean the water, adding new fish or cleaning the tank. I also use it if I seeyl my fish are struggling (look ill, fin damage, etc). This product is a must have for aquarium owners. It doesn't take much to help the tank so the bottle lasts quite a while... 5 ml per 10 gallon tank. If you have a fish tank/aquarium and aren't using this product, go get it! It is keeping my fish tanks and my fish healthy and thriving! A must have! 10 out of 10!

Great for adding fish

TrinR April 10, 2026

[This review was collected as part of a promotion.] I am a big fan of API Stress Coat. This is a product I use every single time I add a fish to my tank because it works. This is made to make your tap water safe for your fish tank. It also gives the fish a coating that helps them adapt to their new home. I have used Stress Coat for a very long time and have never been disappointed. It’s a product I cannot go without and I highly recommend it.

Works great

ShatarahR April 28, 2026

[This review was collected as part of a promotion.] I simply love this product and brand. I’ve used it for years and it really makes a difference in my tank. It’s really easy to use and the directions are clear. The cap doubles as a measuring cup so it’s really all in one. I use it when adding new items, cleaning the tank, adding fresh water, or adding new fish.

Great stress reducer for fish

Soledad2345 February 6, 2013

This is a great product for reducing stress in fish. A few drops in the fish tank water is all that is necessary to calm the goldfish.
