Tropica CO2 Bubble Counter, Check Valve & DiffuserTropica's CO2 diffuser contains a bubble counter, reflux valve and diffuser in just one unit. The bubble counter enables easy and accurate CO2 dosage, since it is easy to count the big bubbles inside the chamber during adjustment. A reflux valve prevents the aquarium water from being sucked backwards, which is possible when the bottle gets empty, or in case you use a magnet valve to turn off the CO2 supply during the night.

This is probably the worst product I've bought for my dog. These toys have the durability of a cup of jello, my small dog seen in the photo destroyed it in one night. Small dog, big dog or puppy, buy them high strength durable toys, my dog was smart enough to not swallow any small pieces she bit off but I cant say other dogs won't swallow the small pieces. I don't recommend this product for any dogs what so ever!
