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.

A good shoe from a trusted brand
Size: 13 Wide, Color: Medium Natural Nubuck, Size: 13 Wide, Color: Medium Natural Nubuck
I'm mostly happy with these so far. They're generally well made, they look great, and I know they'll last a long time. They're real leather, which is always greatly appreciated in this synthetic era. They are pretty dang supportive and comfortable overall. They're lightweight and the price is right. But there are a few negatives, mainly on the comfort front. The right shoe fits perfectly, but the left one isn't quite right. It feels like the top of the heel is stitched a little too tight, such that it digs into the back of my heel when I walk. Now, this isn't uncommon for me with new shoes, but I do kind of expect better from Rockport. The other issue is that the shoes feel a little bit slippery on low pile carpets and tile. Now I'm sure both of those issues are temporary, and will resolve as the shoes break in. Still, they're noticeable. What can I say? They're Rockports. You know they're going to be solid shoes. I almost love these shoes, and really, I'm sure in a few months, when they're fully broken in, I will love them unreservedly. But not quite yet.

Sharp looking dress shoes
Size: 14 Wide, Color: Medium Natural Nubuck
These shoes look great in person and have a clean, classic style that works well for the office, church, or more formal occasions. The natural nubuck gives them a nice appearance without being overly flashy, and they look more expensive than they actually are. The fit was good in the wide size, and they were comfortable right out of the box. The overall quality seems very good, with solid construction and materials that feel like they should hold up well over time. For the price, they're a good value and a nice option if you're looking for a sharp looking pair of dress shoes.

All day comfort!
Size: 12, Color: Grey Nubuck
I was looking for a pair of dress shoes that I could spend a lot of time in and be comfortable. I am happy to report that I’ve found them! I’ve always heard a lot about the Rockport brand, but never wanted to cough up the money that I do for say, Hoka athletic shoes. I can now see what folks do. Very comfortable right from the unboxing. My feet are so happy. The shoes themselves look great, and feature a really strong build quality. The price is a little on the steep side, but I’m learning you get what you pay for in most cases. Definitely a great product that I won’t hesitate to purchase again when needed.
