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.

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+ 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 🐠

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!

Not just for aquariums

BeatriceC April 14, 2026

[This review was collected as part of a promotion.] I use this not in an aquarium but for plants in a semi hydro setup. I have several anthuriums in my collection that were getting crispy edges from the minerals and chlorine in my tap water and just a drop of this in a gallon of water seems to help doing wonders. It's still a bit too early to tell but seems promising! The bottle is large and will last me a few years at the rate I'm using it so definitely worth its value.

A must have!

JessicaS April 28, 2026

[This review was collected as part of a promotion.] Stress coat is always a must when doing water changes or adding new fish to our tank. The instructions are clear, and easy to follow. We have a 65gal tank and this bottle can last us a while! Our fish seem to be better protected and we haven’t lost any while using this product!

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.

Good!

ClaireS April 9, 2026

[This review was collected as part of a promotion.] Once the product made it into the water, the scent was undetectable. The fish didn’t seem to care that we added anything to their water so that was a plus! I believe the product worked as it was supposed to!
