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.

Dermatologist recommended it!
Size: 1.3 Ounce (Pack of 1)
This is my 11th order of this product. I originally started using it a few years ago when my dermatologist recommended it during a period of hormonal acne. I’ve been using it ever since. I have very sensitive skin that usually reacts to almost everything, either with redness or breakouts, but I can use this cream comfortably without any issues. It is very gentle, deeply hydrating, and has become a permanent part of my skincare routine. It is definitely worth the price. Even a small amount provides excellent hydration and it lasts a long time. I also love that it has a natural ingredients and is fragrance-free.

Game changer.
Size: 1.3 Ounce (Pack of 1)
I moved out to Arizona back in 2020 and shortly after that, I became a reptile. My skin would become flaky and peel and I tried several different types of facial creams and lotions with no luck. I went to a dermatologist who recommended CeraVe, and it did help my skin to an extent. It took care of the flakiness, but I would still see the dryness, especially when I looked in the mirror up close. I recently was on Google doing a search and came across this brand. I thought I’d give them a try and though I was skeptical, my skin has not looked this good in years. My skin feels smooth, hydrated and NO greasiness. I highly recommend this product.

Cleared up my flaky skin problem, helps keeps my facial skin soft year round
Size: 1.3 Ounce (Pack of 1)
I bought this full-size tube of Avene Hydrance Optimale Rich Hydrating Cream after falling in love with a small sample tube that came in a subscription box. At the time I received the sample, I was battling an unusual case of dry flaky skin that was embarrassing. Within a few days of regular use, my skin looked like new. Soft and clear. The tiny sample lasted a long time, so I didn't hesitate to buy the full-size tube even at this price. I use this every morning and night after cleansing my face. My skin stays soft, even with the dry winter skin and drying indoor heat. My makeup glides on smoothly. This is my go-to moisturizer year round now. Another reviewer mentioned being concerned her product may be counterfeit. I only buy products like this when it says Sold by Amazon and not a third party so I make sure I get authentic, fresh products every time.

Avene RICH face cream
Size: 1.3 Ounce (Pack of 1)
This is a good product that was recommended by my Dermatologist. As written in a previous review, I prefer the LIGHT product. This is very good but too heavy for my face.
