Reduce Stress in Your Tank

All animals including fish, shrimp and turtles react to stress in similar ways that humans do. Stress can weaken their immune systems and reduce their ability to fend off illness, resulting in poor health and body condition and loss of color. Minimizing and removing stress agents in the aquarium is critical to ensuring the health and well-being of all aquatic creatures by reducing the opportunity for harmful bacteria to grow and spread.

Changes to a fish's environment can cause stress that robs them of essential nutrients and can weaken their immune system. Leading causes of stress on fish and other aquatic organisms is poor water quality, bagging and shipping from the store to your aquarium, water changes, and new fish additions. DrTim's Aquatics First Defense for Freshwater Aquariums is scientifically designed to provide stress relief and naturally support fish immune systems with vitamins and immunostimulants.


First Defense contains a mixture of vitamins and immunostimulants that work together to help fish and other aquatic organisms adapt and cope when introduced to new environments and stress that can occur with poor water quality conditions. Consistent dosing after tank environmental changes is your first line of defense to support fish health, while also promoting healing and wound repair.

DrTim’s Aquatics First Defense works to provide nutrients that boost the immune systems of fish and aquatic creatures by neutralizing chlorine and chloramine, buffering against pH level changes, and detoxifying heavy metals. Our formula should be added to the aquarium during water changes and at any point when fish are showing signs of stress.

We recommend using a minimum dose of 1 teaspoon (5ml) per 10 gallons of water during new aquarium set-up, when adding new fish, with every water change, and after routine tank maintenance. *Caution: DO NOT add First Defense on the same day as Eco-Balance or Waste-Away.

I bought it again!
Size: King (20" X 36"), Color: 07 - Pink - Zipper, Number of Items: 2
This is the 5th time I have bought this pillowcase. It's exactly what you would want - zipper that works, great feel to the satin, color stays constant, and it fits nicely. Also washes well - just throw it in the washer with everything else!

Sleek shear soft cool zippered pillow cases
Color: 07 - Green, Size: Queen (20" X 30")
I'm a huge fan of bamboo fabric. It feels great to wear and so it also feels good to sleep on, especially during hot and or humid spells. Pillowcases came in a pack of 2 and were well packaged and arrived undamaged. Shipping was very fast. Cases appear to be well made. they are a lovely soft green which is perfect for a restful bedroom setup. As expected the fabric is soft and relaxing against the skin, it seems to retain a cooler feel than cotton.Bamboo tends to be a thinner fabric that is light and once damp, dries pretty quickly. Perfect for folks who run hot normally and need extra cooling during the summer or people who sweat at nigh. Cases are zippered and zippers worked well and appear nicely sewn in and decent quality. At night, slept very well. I think this is a good product and like the price point a lo. Will be looking to get another set very soon!
