What Does Stress Coat Do?

API Stress Coat conditions tap water to make it safe for your fish.

But how does Stress Coat actually work?

Stress Coat removes chloramines, ammonia, chlorine, and heavy metals from tap water that might be harmful to fish health.

The product contains Aloe Vera extract, which is great when Dealing With Stressed Fish In A New Tank as it helps reduce fish stress by as much as 40%. This promotes wound and tissue healing, thereby enhancing fish health.

This isn’t all that Stress Coat does:

It also reduces the loss of electrolytes in fish while you’re netting or handling them, performing your monthly water change, or starting an aquarium from scratch – all the situations where your fish tend to be under stress.

API Stress Coat Ingredients

The Aloe Vera aspect of this product is what makes it absolutely incredible at conditioning your fish tank water.

Aloe Vera promotes the healing of wounds and damaged tissue in fish, thereby improving their health and prolonging your fish’ lifespan. Aloe Vera is a powerful natural ingredient that promotes the overall well-being of your pet fish.

When Should You Use API Stress Coat?

It would be best if you used API Stress Coat every time you’re exposing your fish to any form of stress.

The below situations would be an appropriate time to use Stress Coat:

What Are The Benefits of Using Stress Coat?

The benefits of API Stress Coat make it one of the best water conditioners available in the market today.

  • Cleanses and detoxifies tap water by removing chlorine, chloramines, ammonia, and heavy metals. In short, it helps you get rid of all the elements that may cause harm to your fish.
  • Aloe Vera extract promotes the healing of wounds and injured/ damaged tissues in the fish and quickens the regeneration process.
  • Aloe Vera extract also forms a slime coat on the fish’s body to serve as a barrier to electrolyte loss in the fish, which further promotes overall fish health and well-being.
  • Reduces fish stress by as much as 40% during fish handling and water change.
  • Improves the overall quality of water.
  • Promotes healthy fish growth.

How Long Should You Wait To Add Your Fish after Using Stress Coat?

The most common suggestion you’ll hear when you ask this question is to wait for at least 24 hours before adding fish.

This allows the tank to start ‘cycling,’ in which beneficial bacteria grow in water.

However, with API Stress Coat, there’s no waiting. It shows its effects almost immediately, which means you can add fish to your fish tank right away!

And no, the product won’t harm your fish.

How Often Can You Use API Stress Coat?

You can use API Stress Coat every time you change your tank water. It would be best if you used it at every water change.

Now, the question is – how often should you change the water in your fish tank?

If your fish tank is heavily crowded, you should replace 15-20% of the water every week or two.

This means that you can use API Stress Coat every two weeks, that is, with every water change.

How Much Stress Coat Should You Use?

Tank SizeQuantity of API Stress Coat
10 U.S gallons (38 Liters)5ml
240 U.S. gallons (912 Liters)120ml

240 U.S. gallons (912 Liters)240ml

API Stress Coat Comparisons with Other Brands

API Stress Coat is one of the best tank water conditioners available in the market today for all the right reasons.

To prove this, we’ve compared API Stress Coat with some of the market-leading products for you.

Stress Coat vs. Prime

When we compared API Stress Coat and Seachem Prime, the first and the most notable difference (an edge for API Stress Coat) is that Seachem Prime is only a water conditioner.

In contrast, the API Stress Coat not only conditions the water but also reduces fish stress.

Seachem Prime works great at conditioning freshwater and marine water. It removes chloramines and chlorines (basically, it breaks the chemical bonds) and rid the water of nitrite and ammonia. It also enhances the quality of water by providing essential ions. It’ll also work well when it comes to removing heavy metals from tap water.

However, the API Stress Coat does all of it and more!

It removes heavy metals from tap water far more efficiently. And the best thing about API Stress Coat is that it reduces fish stress by up to 40%. It promotes wound healing in fish. So, if your fish is injured, the API Stress Coat will help you make your fish thrive again!

The only edge, we would say, that Prime has over Stress Coat is that a small amount goes a long way, making it more cost-effective in the long run as compared to Stress Coat.

StressZyme or Stress Coat

StressZyme and Stress Coat are both excellent products from API. They’re both targeted for different purposes.

While the API Stress Coat is focused more on conditioning the water to make it safer and healthier for your fish and reducing the fish stress, StressZyme is targeted at keeping your fish tank clean.

API Stress Coat is used when you add new fish to your tank, change the water in the tank, or if your fish has gotten injured.

On the other hand, StressZyme adds beneficial bacteria to your fish tank that feed on organic fish waste and sludge and help you maintain a clean aquarium.

API Stress Coat works on improving the water conditions, whereas API StressZyme improves the tank conditions (how clean your tank appears).

API Stress Coat keeps fish healthy and active, and StressZyme reduces the amount of maintenance work you’ve got to do.

What Is Best? Prime vs. Stress Coat vs. StressZyme?

If you compare API Stress Coat, Seachem Prime, and API StressZyme, you’ll see that Seachem Prime and API StressZyme serve a single purpose.

Seachem Prime is a water conditioner, and API StressZyme is a water cleanser.

But API Stress Coat serves two purposes; it’s a water conditioner and a fish stress reducer.

It not only ensures that your water is free of all harmful elements but also promotes wound and tissue healing in affected fish.

So, we’ve got a clear winner here – the API Stress Coat!
