It feels slimy, which is great because this is supposed to replace your fish's slime coat. I heard that it clogs one's filter and, so I switched out to a competitor and I noticed that my prefilter and filter don't get clogged as much. That said, I will still buy this in a pinch every time because it is readily available at any pet store and it's so much cheaper than any other option. I hope they keep making this, and I'm 99.9% certain that they will because it's so cheap and popular. This is like the standard of all stress coat replenishers and dechlorinators. Better ones exist out there, but this isn't going to kill your fish or anything. For record, I have fresh water fish in a tropical setup without plants. I have a rotating cast of characters that include Corey ... MoreIt feels slimy, which is great because this is supposed to replace your fish's slime coat.

All I can say is GET IT! Have you got snails? Noticed fish glass surfing? Noticed the wood in your tank looking almost white from the acid in the water? If you answered yes to any of the above this is what you need! I use it in conjunction with Prime on every tank clean and refill and my aquatic life dont stress whatsoever. Its adds a layer of protection over them, you could say it wraps a little hug of security around each living creature, you will discover that due to less stress, theres no chance of death as a result of shock!

API Stress Coat is a phenomenal product. It reduces stress up to 40% by making tap water safe for fish; in addition, it replaces the protective slime coat. The product is fortified with soothing aloe vera which promotes healing from torn fins and skin wounds, reduces susceptibility to disease and infection, reduce electrolyte loss. Stress coat also removes chlorine and chloramines and neutralizes heavy metals that are found in tap water.Aloe barbadensis (Aloe vera) contains a colorless mucilaginous gel called aloe vera gel. Quite a few biological effects of aloe vera including immunostimulation, increasing growth performance, improvement of wound healing in fish have been researched and founded. Reactive oxygen species (ROS) are continually produced in animals ... MoreAPI Stress Coat is a phenomenal product.

Quite a few biological effects of aloe vera including immunostimulation, increasing growth performance, improvement of wound healing in fish have been researched and founded. Reactive oxygen species (ROS) are continually produced in animals during normal aerobic metabolism that can damage most cellular components leading to death. Fish possess an antioxidant defense system to reduce the negative effects of ROS. Fish are aerobic organisms that are susceptible to ROS. Therefore, aloe vera is a great healing inhibitor and immune booster for fish and their protective slime coat.I have been using this product for over 15+ years and its a miracle cure that increases the survivability of my fish. In my personal opinion, I would never use this product to simply condition water instead use a primer to get the job done. However, I do use this product in conjunction with water changes to try to destress my fish and boost their immune system since tap water is damaging to a fish's slime coat. Last but not least, I highly recommend pouring in the stress coat after conducting the water changes and not before or during since the stress coat will smear onto the aquarium glass causing the glass to appear dirty and/or blurry. You can easily clean it up with a scraper, but it is just beneficial to save time and effort.

This helped with stress from fish bought online. The fist batch without this had some die. The second batch with it all lived. My water parameters were good for both batches. Both of the shipped fished arrived in cold water and were stressed. But the second batch I had added stress coat along with my Prime and it made a difference. I still use the Prime though because I trust it. Something about the aloe in this does make a difference.
I do not use this as a product to treat my tap water. For that, I use prime which seems to just be far more concentrated and I seem to have better results with prime as a conditioner and ammonia treatment than I did with this stuff.That does not however take away the ability for this product to be effective in treating things like fin rot and for stress. I am 100% confident that the use of Stress Coat in my quarantine tanks and when acclimating fish has lead to me having a much higher success rate in nursing fish back from illness or the scary acclimation process in which you can lose fish easily with one simple mistake.I've been using this product in conjunction with multiple medications and it definitely keeps the fish healthy, calm, and eating while in ... MoreI do not use this as a product to treat my tap water.

It definitely helps stunt the rotting of fins and spread of fungal/bacterial infections when used with other medicines.This product is a MUST have for those of use who quarantine and nurse less than optimally healthy fish back to satisfactory health. If you're serious about fish keeping, always quarantine and always use Stress Coat!
I was starting a new tank, followed all the rules, but when I put my fish in they just weren't right. After my first water change they were a mess! One of them even started shaking, but all my water parameters were fine and consistent. I added this to the tank, just the standard dose, and within an hour they had all calmed down. After a day they were starting to swim around, and three days later they're happy, playing, and eating normally. I absolutely attribute it to this stuff. I also had to quarantine a fish that just wasn't right from day one. I added this to his tank as well and I think it helped him survive. I now have this on auto delivery so I can't run out. I'm a believer!
