Not Just for Fish! Also Great for Plants!
I don't use this for an aquarium. In fact, I don't even have an aquarium. It was recommended by a plant expert to use in the water I use to water my plants. Hard, chlorinated water filed with chemicals is not good at all for plants and while it won't kill most of them, some of them end up unhappy over time. When I first heard about this product, I was skeptical. Could it really help with my plants? Well, upon researching, apparently so! It removes not only chlorine, which is in all tap water, it removes chloramines and heavy metals. They're all bad for fish and bad for plants as well! The price is low and I use just 2 - 3 drops with each gallon of tap water, immediately takes action. No waiting! I bought the 4 ounce size and at this concentrate, that much will last me years (and I have a lot of house plants. There's not much odor, it's clear and a little thicker than water. This is a no-brainer. I'm happy I discovered it.

Super Value Of Great Product
I've been using this stuff for years and I usually buy local but I saw the price , already had something in my cart so I added it to save me a trip to the pet big box store . I thought I was getting the usual small bottle and when it arrived and it was 16oz I immediately thought there was a mistake . I went back and looked and it was correct . I usually get 4oz for the same price (unless on sale) locally (big box per store) and I didn't have to fight mall traffic only to search forever for a parking spot . When starting a new setup , doing a partial water change , or just adding water this stuff is a must . I add 1 gallon at a time to my 50 gallon tank and the 1 gallon mark doesn't exist but I measured out the correct amount the first few times and now just approximate it using the cap to just about double what 1 gallon calls for . It works instantly , unlike some others , so I can do the needed addition at my convenience and the fish don't seem to mind the fresh water going into the tank . No color , no change in chemical and biological balances and no smell . If you've got a fresh water tank you need this stuff .

A must have
Stress Coat is wonderful stuff. One of my Orandas was laying eggs and one of my males tore off a few of the scales on her side overnight. I put her in a hospital tank with Stress Coat and she was visibly better within a few days. And within a few hours after the move she had settled down and wasn't as agitated. Definitely something every aquarium owner should have on hand.

Nice product
It looks to work well. I see some bubbles in the water surface after using this product, but it may not be a real issue.

The Fish Like It
We have a water garden on our deck. It holds about 7-8 gallons and we have goldfish and aquatic plants in it. The fish cannot tolerate tap water because of the purification chemicals, so we were buying spring water at the grocery store. Using API Stress Coat is much cheaper because we can now use tap water. We add .5 ml per gallon and it de-chlorinates it. Plus, it has aloe vera to help heal and fin damage and prevents stress from water imbalance. It helps promote clear water.

All API products are good. Stress Coat is a miracle medicine.
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 underwater in 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 REVIEW and 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 water three 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 floating duckweed 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 ). //
