This product has been a game changer for me.Firstly, the 16-ounce size is very economical. It lasts quite a while even with regular use, which is great for someone who doesn’t want to constantly repurchase supplies. The application process is straightforward and easy – just follow the instructions on the bottle.The most impressive part is its effectiveness. Since using this conditioner, I’ve noticed that my fish are visibly healthier and more active. Their colors are more vibrant, and they seem less stressed, especially after water changes or when introducing new fish to the tank. The product claims to reduce fish stress by 40% and it really seems to live up to that promise.Another major benefit is how it treats tap water. The conditioner neutralizes chlorine, chloramines, and heavy metals present in tap water, making it safer for the aquarium. This is crucial for the wellbeing of the fish and helps maintain a balanced ecosystem in the tank.Overall, I highly recommend the API STRESS COAT Aquarium Water Conditioner to any aquarium enthusiast. Whether you’re a beginner or an experienced fishkeeper, this product is a must-have in your aquarium care toolkit. It’s a small investment for the huge benefit it brings to the health and happiness of your aquatic pets. ### ⭐⭐⭐⭐⭐ Good product *by on Reviewed in the United States June 16, 2026* This is very good this is my second time buying this is relliabel and cheap for its price the size is very good, the odor smells like aloe Vera. ### ⭐⭐⭐⭐⭐ All API products are good. Stress Coat is a miracle medicine. *by on Reviewed in the United States December 15, 2012* I add API Stress Coat to all new water before it goes into my aquarium.I also add a enough hot water to make it the same temperature as the aquarium.Add an extra dose when add fish.Add an extra dose whenever fish appear ill or stressed.It truly is an first-resort, miracle medicine for fish.THE FOLLOWING REVIEWS ARE FOR ALL OF MY AQUATIC PURCHASES.I always read two dozen or more User Reviews for any product I buy.Amazon is honest and prints both the good and the bad reviews.I bought the following products from Amazon:>*****> Hagen Marina Ecoscaper Hydrocotyle Silk Plant.I am really pleased with this plant.And the fish like it too . . . no rough edges.It is just as pictured and looks so realistic.>*****> Hagen Exo Terra Water PLANT, Duckweed.It looks and floats just like real duckweed !I showed it to the aquatics people at Petco and they were impressed.>*****> Hydor Theo Submersible Aquarium HEATER 25W UL.Very small and easy to adjust; plus it can be placed completely underwaterin any position: vertical, horizontal, or on an angle.>*****> Hagen Elite Underwater Mini FILTER for up to 3 gallon tank.>*****> Hagen Elite Mini Internal FOAM 5 PACK replacement sponges.This is an excellent filter for my 5 gallon tank.It is well-made and powerful and could filter a 10 gallon tank.To reduce the water current to make it easy on my fish, I TOOK THE ADVICE FROM A USER REVIEWand bought a 5-pack of replacement sponge filters and used one sponge to completely cover the outflow valve.I also put a wee bit of the foam filter in the Venturi diffuser aerator.I set the aerator to low, which still provides ample aeration.I set the green filter power dial on the side of the filter to low to be just enough to create a good supply of aerating bubbles.I operated the aquarium for over a month without fish so that the water would be biologically perfect for them.Petco checks water samples for free.That little $9 dollar bio filter is just a wonder and so easy to maintain.Unplug the filter and remove it from the aquarium, then syphon off some aquarium water ( never use tap water) and squeeze the foam sponge in clean aquarium waterthree times or more until the final wash water is almost clear, then replace the sponge in the filter.I now have 5 Von Rio "Flame" Tetras doing very well in their new home.They do best when in a group of 5 or more, and in a low light environment, so I must have low-light live plants.I have a well-planted 5 gallon corner-type aquarium with a lid just for these 5 beautiful and hardy little orange fish.To provide shelter, there are lots of live Java ferns and wisteria plants at each end, plus the hydrocotyle silk plant to hide the filter and heater, and the plastic floatingduckweed to provide shelter from above.I purchased the silk hydrocotyle and plastic duckweed, because these live plants would perish in low light.Fish, like all living creatures, need shelter from real or perceived threats.Stress is the cause of most of life's mental and physical illnesses.For many years, I have purchased almost every type of product from Amazon and never had a problem.Products are as advertised, or better, and Super Saver Shipping is fast and dependable.I recommended all of the above products to my friends.I tell everyone to save money and buy through Amazon ( including the aquatics people at Petco ).// ## Frequently Bought Together - API STRESS COAT Aquarium Water Conditioner 1-Gallon Bottle, Model Number: 317163100851 - API Stress Zyme Freshwater and Saltwater Aquarium Cleaning Solution 1-Gallon Bottle - API QUICK START Freshwater and Saltwater Aquarium Nitrifying Bacteria 32-Ounce Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/5435441-api-stress-coat-aquarium-water-conditioner-1-gallon-bottle-model](https://www.desertcart.pt/products/5435441-api-stress-coat-aquarium-water-conditioner-1-gallon-bottle-model) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-28*
