EHEIM CO2 diffuser 400lCO2 Diffuser The diffuser atomizes CO2 gas into numerous bubbles, which increases the contact area and allows the CO2 to dissolve rapidly in the aquarium water. The integrated bubble counter provides a visual means to monitor CO2 dosing. A general guideline is to aim for approximately 20 mg of CO2 per liter, which translates to about 10 bubbles per minute for every 100 liters of water.

The pink is darker than the image portrays
Color: Infinite Pink
The pink color is significantly darker than the image shows. It’s like a dark red rose color in real life, not so much a hot pink like the listing shows

Still A Fossil Fan
Color: Black, Color: Black
I have been a fan of Fossil products for many years. When I needed a new wallet I was happy to have found this style on Amazon. I travel fairly often so I knew that I wanted a leather wallet that had a removeable hand strap, ample card storage, and a zip closure. This wallet was exactly what I was looking for. The strap is sturdy and zipper is really smooth. The inside of the wallet is very roomy, with multiple pockets (my samsung phone fits inside). There are also two zipper sections (one interior and the other exterior). There are also several places for your ID, cards, etc. I have been using this wallet for over a yearit now and I must say that it has held up really well. There are no pulls/ tears in the stiching or issues with the strap and the zippers still work like new. It's a great option to have on those days when you just don't feel like carrying around a handbag. I would definitely buy this item again.
