API 237ml/8oz Stress Coat
API Stress Coat is an essential water conditioner for any aquarium owner. It is a multi-purpose product which is scientifically proven to help relieve fish of stress, as well as help to restore tissue damage. Stress Coat works by forming a synthetic slime coating around the fish, helping to replace the natural secretion of slime produced by fish. This can often be halted by stressful situations, leaving the fish more vulnerable to disease and infection. It is a multi-purpose solution which also helps to remove ammonia, chlorine and chloramines from tap water. It is advised that this product is used when adding new fish, during water changes, or when beginning a new aquarium. Available in 118ml, 237ml, 473ml and 1.9 litre sizes.

I was low on my stress coat plus and was looking for 2 new freshwater angelfish. That was afew weeks ago and both are getting bigger. API stress coat plus does wonders and have been useing it for years. It does calm the tank down because API has aloe vera that calms your fish new and older ones. Thanks for all the great work Petco in Covington, Louisiana and yes online...Steve

If I could give zero stars I would! I bought this yesterday and put the amount directed in my saltwater tank. It was supposed to "lower the ammonia and nitrates." After 3 hours, I went and checked on the ammonia and nitrate levels to find that there was no change whatsoever. So , I doubled the dose, waited till morning, and STILL NOTHING happened! Waste of money. Instead, buy Seachem Purigen. It works 100%, while API STRESS ZYME+ does NOTHING!

I use Stress Zyme in my tank. I just happened to stumble upon this website & I searched for it & they had it. This is a great size bottle & it should last for a while. Company was fantastic, shipping & received very quickly & the price didn’t break the bank. Totally recommend this company & will definitely order items from them again. A+++ 😀

I love this product. I have been using it for several years now. I have several of my fish for many years now. It gives amazing water clarity and truly helps protect your fish.
Ever since i was recommended to get this API stress zyme by my son, i was a little sceptical of these products but now id highly recommend it for all aquarium lover's. It adds important & essential bacterium to the water which eat the sludge & fish waste that accumulates in the filtration system. I'd also recommend API stress coat too, my fish tank is so clear & the live plants are thriving ever since ive been using API stress zyme. If you don't want to change the aquarium water on a regular basis, get yaself some API stress zyme & API stress coat & you'll have far less water changes than usual. Highly recommended products if you want to keep your aquarium looking great & water in amazing condition, get these products asap. Cheers!
I fill my 5 gallon buckets up in the tub and add this while the water is running. Disperses well. I haven't taken any chemical readings, but I just assume it's doing what it says it does. dosing amounts are on the label. I keep a 5 gal bucket of treated water on hand for replacing evaporated water--product seems to work fine. my fish are pretty healthy and I do very infrequent water changes--two goldfsh and about 10 kuhli loaches.
I always recommend Indiefur above every other seller as they sell genuine product at right market price, unlike any amazon or flipkart seller who sells the same product at a higher MRPs then the original market price. Also the delivery is fast & well packed. They take care of the cuatomer preferences & they deliver the product fast & seamlessly. Good work Indiefur team. Thank you!!
I ordered twice from AquariumKingdom. The first is Stress Zyme and Stress Coat, and the second one is API Bettafix. These things make changing water easier for me and help to improve my fish's health. However, I'm not too sure if the BettaFix helps cure my fish's popeyes. I change the water every two days before the BettaFix treatment, but nothing happens. After the treatment, my fish's eye colour changes, but the swelling decreases a bit after two days Anyway, the products come in good shape and good packaging. Fast delivery. Will order again if I need anything for my fish.
This is so much cheaper than the ones at Petsmart. I would high recommend just buying conditioner here. I can't say that I love this product because I can't see it working in my tank, but I guess it did the job since my goldfish is still alive, and I've changed the water twice already. Perfct for a 10 gallon tank, which I use for my goldfish. I don't think I have to buy another bottle of conditioner for a while because I only need, I think, 5mL for every 10 gallons. So glad I found something cheaper than what's at Petsmart.
This single product does what so many other companies want you to buy multiple products to do and it does it effectively so. This product should be used for:-Helping to cycle a new aquarium-Removes chlorine, chloramines and detoxifies heavy metals making tape water safe for fish-Replaces the slime coat and keeps fish slick and coated-Help to heal damaged fins and scales-Works wonders with fin regrowth-Wonderful for aquarium plants-Reduces fish stress from handling and new tank syndrome (to be added when adding new fish to an aquarium)-Helps protect fish against diseases and infections-Keeps fish's fins long, vibrant, and beautiful (even if it is not being used for fin regrowth)API products are wonderful and I honestly have never seen a more versatile ... MoreThis single product does what so many other companies want you to buy multiple products to do and it does it effectively so.

Highly recommend, there are few other products that you will need for your aquarium other than this one.
