ATKv2-I

The Neptune Systems Automatic Top-Off Kit v2 is a simple, standalone, and complete solution for replacing water lost to evaporation. The new aquarium hobbyist has many challenges, but none is more annoying than the chore of adding water, every day, to make up for that lost to evaporation (a.k.a. topping off/up). This alone usually makes the automatic top-off (ATO) device the first piece of automation equipment purchased.

The Automatic Top-Off Kit is designed to not only be super-simple to install and use, but it is unique in the market as an ATO device with three layers of redundant monitoring and water-level control. The ATK does the work for you, while at the same time protecting your tank and your home

Nice size, the quality is changing. It is softer I believe than it used to be.
Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large
Not sure if something has changed in the way this product "Barkbone" is made. I bought this many times before and it lasted. Today, on my dogs first day of use, he had chipped through the material, and already destroying it. he has had it for less than 3 hours.

Great Product!

My dogs love their dental chews! This product is durable and the perfect size for each of my dogs. I've purchased two of them (medium and large). One of my dogs is an aggressive chewer and this product is holding up. Hartz makes great pet products. I'm very happy with the product.

Winnie Loves Them!
Size: Medium (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
My Winnie is an aggressive chewer and she loves these bones. They're indestructible and they must be delicious because she works on them every day. I was a bit concerned when they were out of stock for a few months. Please don't discontinue them!
