They have upgraded the design for the "green ball" people reference loosing is no longer - it's permanently a part of the design now. The indicator works great. I have it on the opposite side from my diffuser. It does take about 1-2 hours to respond to CO² levels but that's standard. Made from acrylic and not glass so you can't break it. Review: Easy to recognize the color change - The product is not only very accurate, you can even see the color change without aquarium light. And it’s so easy to clean. The best part is the green dot on the top, even for people like me with no sense of color, it’s easy to see and read if CO2 in tank is appropriate. ## Features - [Colorimetric design] Built-in colorimetric module, monitoring CO2 content is more clear and convenient - 【 Acrylic material】 Made of acrylic, which is transparent like glass but not breakable, making it more durable. - 【Detachable design 】 Elegant shape; It is easy to drop the solution and cleaning - 【Reinforced packaging】 Customized packaging to protect product safety to the greatest extent. - 【 Complete Set 】 Package includes CO2 tear drop monitor, indicator solution and suction cup. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BBLV3MXN | | Allergen Information | Preservative-Free | | Brand | Clscea | | Brand Name | Clscea | | Customer Reviews | 4.2 out of 5 stars 162 Reviews | | Included Components | NO | | Item Type Name | NO | | Item Weight | 0.04 Kilograms | | Item weight | 0.04 Kilograms | | Liquid Volume | 0.51 Fluid Ounces | | Liquid volume | 0.51 Fluid Ounces | | Manufacturer | Clscea | | Target Species | Fish and Plants | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Clscea - **Item Form:** Liquid - **Item Weight:** 0.04 Kilograms - **Liquid Volume:** 0.51 Fluid Ounces - **Manufacturer:** Clscea ## Images ![Aquarium CO2 Acrylic Drop Checker CO2 Indicator (Tear Drop & 15ml) - Image 1](https://m.media-amazon.com/images/I/71sb1wtKliL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does what it needs to! *by S***. on 16 January 2023* Super easy to setup and install.
