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.

bag came ripped
bag came ripped so the chewy pig ears were not chewy they were hard, I didnt even give them to my dog. The worst part is they are not returnable or refundable - what a waste of money So not acceptable.

Awesome quality balls -- my dog loves them!
Color: F) 3-Pack (2.5" Balls)
Love this 3 ball set and variety and quality. These are the 2.5" size, similar to a tennis ball size give or take. The fun citron yellow one is the thickest + heaviest, very bouncy, and tough. The blue is still tough but not as thick or bouncy, a bit more flexible. And the clearish one is the lightest/flexible and is glow in the dark [although we haven't tried that part yet]. I have a 7month old 40lb girl who is becoming like a power chewer on some things -- but hasn't done that with these. She can play, mouth them, chew them, not even one knick or anything. Yes! The citron and blue one we leave out all the time in her little toy box. They have holes in the middle and have used them to hold thinner bully sticks and other treats. The blue one is fun to put smaller treats inside that she can work out like a puzzle. Obviously they are fun for fetch! We leave the other up and only get out when we can play with her because label said it is not a chew toy so we didn't want to take chances. Overall super fun and cool and good quality, human and dog approved LoL. ***We ordered the 2 set of 4" balls, blue and purple [they are same consistency of the blue ball] and love these too! Very fun and good at using with treats the sticks too, plus these don't get lost under sofas and furniture like the smaller ones, a big plus.

Glow and play - pups favorite!
Color: A) 2-Pack (2.5" Balls)
I can't say enough good things about this glowing fetch ball! It's perfect for outdoor play at night—my dog loves chasing it in the dark, and the bright glow keeps the fun going even after sunset. What really impresses me is the quality; this ball has withstood my pup's enthusiastic chewing (and believe me, he can demolish a regular ball in seconds). It’s durable and built to last, making it a fantastic investment for any dog owner. If you're looking for a fun nighttime activity, this glowing fetch ball is a must-have!
