Looks cool, great size for my 29 gallon. Easy to set up, need to get another one for my other tanks Review: It’s great! - These are great. I like the circle design as it’s more unique. The drop checker works perfectly and is well made. I made it clap on a handstand out of pure joy at how much I enjoy this checker. ## Features - Easy To Use: It consists of a pre-made 4dKH solution containing the appropriate amount of indicator. No mixing is required. Just fill the carbon dioxide monitor drop checker 1/2 full of indicator solution and place it in the planted tank with the help of the suction cup. - Precise Readings: If the indicator solution is green in color, then appropriate levels of carbon dioxide exist in the aquarium, and no action is required. If the solution in the drop checker changes to blue or yellow, then the CO2 levels in the aquarium are too low or too high, respectively. - Essential Item: You need to be very careful about your plants' health; carbon dioxide is one of their major requirements. This CO2 monitor kit is one of your aquarium kit's most vital items that helps you keep a constant check on CO2 levels in the water. - Quality Guaranteed: The drop checker is made of the highest quality, laboratory-grade, borosilicate glass ​for maximum strength and durability. - Complete kit includes: 1x glass drop checker, 1x bottle of pre-mixed indicator solution (15 mL / 0.5 fl oz), 1x pipette ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C9WM7TKY | | ASIN | B0C9WM7TKY | | Best Sellers Rank | #34,469 in Pet Supplies ( See Top 100 in Pet Supplies ) #54 in Aquarium Test Kits | | Brand Name | JARDLI | | Customer Reviews | 4.4 4.4 out of 5 stars (476) | | Date First Available | July 1, 2023 | | Date First Available | July 1, 2023 | | Item Package Dimensions L x W x H | 4.49 x 3.78 x 1.73 inches | | Item Weight | 1.58 ounces | | Manufacturer | JARDLI | | Manufacturer | JARDLI | | Package Dimensions | 4.49 x 3.78 x 1.73 inches; 1.59 ounces | ## Images ![JARDLI Small CO2 Drop Checker - Image 1](https://m.media-amazon.com/images/I/71M7eBOprqL.jpg) ## Available Options This product comes in different **Pattern** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love this thing *by G***S on June 24, 2025* Love this thing. Looks cool, great size for my 29 gallon. Easy to set up, need to get another one for my other tanks ### ⭐⭐⭐⭐⭐ It’s great! *by P***0 on March 17, 2025* These are great. I like the circle design as it’s more unique. The drop checker works perfectly and is well made. I made it clap on a handstand out of pure joy at how much I enjoy this checker. ### ⭐⭐⭐⭐⭐ Why so blue *by M***E on July 24, 2023* This co2 checker is so blue and waiting for it to turn green. Oh wait, it’s only been 12 seconds since I placed in my tank! If I come back to edit my review, this will mean that it never transitioned to green and that will not be good. Anyway, while I wait, this checker is a perfect size and was easy to fill. It looks better than the traditional co2 checkers in my opinion so I hope it works. ## Frequently Bought Together - JARDLI Glass CO2 Drop Checker – CO2 Monitor Kit for Aquarium Planted Tank CO2 System (Drop Checker with Solution) - Clscea Aquarium Glass CO2 Diffuser Atomizer with U Tube Check Valve Suction Cup Premium Version --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.my/products/549782158-jardli-small-co2-drop-checker](https://www.desertcart.com.my/products/549782158-jardli-small-co2-drop-checker) --- *Product available on Desertcart Malaysia* *Store origin: MY* *Last updated: 2026-05-21*
