It's modern and sleek design adds a neat level of suffistacated aquarium functionality and will work wonderfully with glass Lilly pipes or standalone stock black. I gave it five stars because it came earlier than expected and at a Aesthetic quality I had wanted. My only con is that, like most drop checker solutions, the one that came with this product has outdated directions, or ones that experienced artists will find wron as it does tell you to add aquarium water or (as best I can figure out) to use the solution as a standalone product for Co2 measurement. Well, it's a concentrated solution, so using either of these methods I believe will provide false accuracy. So, with a little planning ahead that problem won't affect you. Just purchase a 4dkh water solution as well and use it in place of the directions. If seller would provide correct information regarding this solution it would make hobbyist's new to Co2 have a much easier time. I have no other problems than this small bit of information and still believe skier deserves 5 stars. ### ⭐⭐ May be a good product, but directions are misleading. *by M***V on September 9, 2017* I am definitely not an expert on drop checkers, but this product seems way off. Instructions say to apply 1.5 mL of the indicator solution to the checker and then place it in the tank. If you do this, the color will remain dark blue forever, and that is because you haven't added any 4dKH solution, which the instructions don't even mention. Also, the instructions say you can get a faster reading if you simply ad 5-15 drops of the CO2 test solution to your aquarium water, which I've read is a completely bogus and inaccurate way of reading your CO2 levels. In summary, the product seems sketchy, the directions are vague, and certain ingredients are left out of the picture altogether. ### ⭐⭐⭐⭐⭐ Great price, super fast ship and the indicator solution works-don't wait or shop around *by N***1 on June 26, 2016* I have a plastic orb drop checker and have been wondering why the solution isn't reading the CO2 levels-it is always blue, so I got this one as a backup and within half an hour it was confirming that the CO2 levels were good with a nice green color. Beautiful shape and I was afraid my Kuhli loaches and corys would go into it-but they haven't. My only regret is not getting one like this earlier. Great price, super fast ship and the indicator solution works-don't wait or shop around, this one was the best price I could find and is glass, not plastic. --- ## 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.tn/products/56874355-bubblefin-aquarium-carbon-dioxide-co2-monitor-glass-drop-checker-solution](https://www.desertcart.tn/products/56874355-bubblefin-aquarium-carbon-dioxide-co2-monitor-glass-drop-checker-solution) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
