After trying another on Amazon, with the best reviews, I had to return it, so I was hesitant buying something that was .1 stars less than the previous one. While the other didn’t work due to a bad reagent (liquid that was bad). This one works perfectly! Setup was less than a minute, the color is deep blue and once it was in my tank for a couple hours it showed my CO2 was at the levels it needed to be, so glad I decided to return the other and buy this one. Both were basically the same price, and this one came with an extra suction cup which is nice in case one gets worn out. ## Frequently Bought Together - FZONE Aquatic CO2 Glass Drop Checker PH Momitor for Aquarium Plant Fish Tank Test CO2 Kit - Fzone Neo CO2 Diffuser with Customized Ceramic from South Korea(S-13mm) --- ## 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.sc/products/485788596-fzone-aquatic-co2-glass-drop-checker-ph-momitor-test-co2](https://www.desertcart.sc/products/485788596-fzone-aquatic-co2-glass-drop-checker-ph-momitor-test-co2) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-27*
