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.

1st one lasted over 3yrs, 2nd started falling apart in less than a week....
Color: Orange & Blue Roller, Size: 7.5 inches (1 Pack), Color: Orange & Blue Roller, Size: 7.5 inches (1 Pack)
My dog really loves this toy. He’s a 5yr old border collie. He doesn’t work at tearing up his toys but he does shake his toys. I bought his 1st Chuckit it indoor football over 3yrs ago. It held up very well and had normal wear and tear I’d expect from a chuckit toy to have. It developed a small tear in fabric about 6months ago. As it was still mainly intact, I let him continue to play with it. Then the tear widened and I felt good time to replace, so I ordered one from Amazon. He was ecstatic to have a new one. I was quite disappointed though as in under a week from giving it to him(he’s always supervised during play so I do know what he does with his toys and he doesn’t work at them to tear them up) I noticed a tear down the seam that was bigger than the other one had for 6months. Over the next few days, tear widened. Now cover is completely off of inside. I’m really disappointed in the quality. I’m not sure if the quality of the toy is less than when I got his first one(which I bought in a pet store such as petsmart) or if for some reason because I purchased on amazon, they are of lesser quality. I do know for a fact as I supervise his play and with his favorite toys(and usually his spendier toys) they get put up when it’s not play time. He has his other toys that he can play with anytime. I have ran also into Kong toys (Wubba) that has come apart quickly in under a month,but those were both bought on amazon and at a retail store, so I don’t know if amazon is distributing toys of lesssr quality or if toy brands that have held up in past (Kong Wubba & this Chuckit football) are just being made of lesser quality. My dog’s style of play hasn’t changed nor has his supervision. That being said, my dog absolutely LOVES this toy. I want other users to be forewarned that I’ve had 2 of this product for my dog, they both developed a tear down seam, that eventually led to outer fabric shell coming off of the inner part of the toy. Yes my dog does shake his toys but 1st lasted over 3yrs, 2nd lasted less than a month and is in worse condition than the first. I may purchase this toy again as it’s one of his favorites just to see if the 2nd one was a fluke. Had I paid more than $6.19(I’m a prime member and it was an add on product) I most likely wouldn’t purchase a third one. I’m willing to see if the third one will last at least a yr. if it starts coming apart in less than a week again, I’ll have my answer which would be that chuckit has resorted to making their toys of lessor quality. I hope that’s not the case because they are one of only a couple of brands I hold in high regard for their good quality and durable dog toys. Please see picture. It’s his toy in less than a month. The outer material came off during play last night. It lasted less than a month from time I gave it to him to play with. 5/22/18 update. I bought him a 3rd indoor fumblr, it last almost 3 months...I ordered him a 4th one. I gave it to him Friday, today is Tuesday, his 4th one is already coming apart at the seams. When I ordered 4th fumblr, I bought 2 at the same time, they were $5.19 each(prime member add on price). I’m glad I did because now they are twice the price at now over $10. I very highly doubt I will buy another indoor fumblr unless price drops in half again. This last one that I gave him 4-5days ago, it hasn’t been his daily favorite toy. He’s maybe played with it a couple hrs each day. My dog really LOVES this toy. I’m moving my rating down to a 1 Star from 2 as this toy has consistently come apart rather quickly. I’m very disappointed in the quality of this toy. He’s 5 1/2yrs Old now. 1st fumblr last over 3yrs, he’s gone through the other 3 in under 6months...had I paid over $10 each time, I probably would’ve stopped after the 3rd fumblr came apart. as it is now, I won’t but any more fumblrs by chuckit at this price....if price drops, after he’s gone through the 5th one I have put up...I may consider it...but not at over $10 for a toy that comes apart through normal play in under 5 days...

Soft, medium quality
Ok value for the money and doggies liked it. Not very durable but certainly more durable than some. Stitching is good and is ok - good toy overall but nothing exciting and not super durable though far better than some toys that just fall apart. And if your dog isn’t a toy killer this will be a great toy!

My dog Ed gives it two paws up
I have four dogs. One is completely in love with his toys. One is so so about them. The two others have no interest. I got this for the so so dog and he liked it, but only in small intervals. He left it for my other toy loving dog, Ed. For him, it was love at first bite. He took it and happily cuddled with it, threw it around, and watched with an adoring look at the flailing arms. The little squeaks thrilled him (to the chagrin of one of the other dogs who hates squeaks). Definitely a great buy and super cute.
