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.

Make sure you know the difference of high back vs mid back versions
Color: Brown, Size: Mid Back
I got a little confused by the reviews since they mix the high back version with the mid back. I thought the arm rests were adjustable and the back had some lean. Apparently only the high back version. That said, it is very nice. Its at least a hundred less than what you'd get at an office depot and it is generously sized and very supportive and comfortable. The assembly was relatively easy, instructions could have been a bit better. The piece connecting the seat and back doesn't sit flush with the mount that attached to the legs which is weird but it feels sturdy nonetheless. Overall it's very nice and the design is really cool, it looks like a 70s race car style seat. Exactly what I was looking for basically. I sort of wish I got the high back version for the adjustable arms and the ability to recline but it is a work chair for me mostly so I guess it doesn't need to lean back, even if it would be nice if it did.

Excellent product. Great value, detailed parts and labels, outstanding construction.
Color: Brown, Size: Mid Back
Outstanding Purchase. The desk chair far exceeded my requirements and expectations. The price was so far below other office chairs that I was concerned that it would be shoddy, uncomfortable, cheap looking and impossible to put together. Materials were top grade, instructions were precise and all parts were market for location with "front and back" labels. Not a screw was missing or misaligned. Since my desk and office are in the Master, really impressed with the color and design. Very comfortable with good back support ,adjustment ease and arm support.. Bravo to your team!!!
