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.

I love this shirt. The fabric is hard to describe, but it’s very comfortable, cool, and soft. If you’re looking for something highly breathable, this is it. The quality is well made, and the zipper is great. I’m not worried about it splitting or the zipper coming off. It’s fantastic, very comfortable, and fits me really well, even though I’m over 6 feet tall. The value for the money is great. I’ve already mentioned how soft it feels, and the appearance is great too. That white collar really pops against the crisp dark black. I know the picture doesn’t capture it well and looks a bit washed out, but in person the black is very black and the white is crisp white, exactly as shown in the listing photos.
