NilocG Aquatics Glass Co2 Drop Checker with 4dkh/PH Solution | Quickest, Most Accurate & Easiest to Use | | Glass Co2 Drop Checker with 4dKH/Ph Reagent Most Accurate Monitoring of Your Co2 Levels

I’ve been using this drop checker in my planted tank for about two weeks now, and I don’t really have any complaints. It’s a small thing, but it does what it’s supposed to without getting in the way — which is more than I can say for a few other ones I’ve tried. First off, the design is clean and compact. It tucks neatly into the corner of the tank and doesn’t draw much attention, which I like. It comes with everything you need to get started, including the indicator solution and a pipette. The instructions were actually super clear — one of the few times I haven’t had to google a setup video just to make sure I was doing it right. I noticed the color change after a couple hours and it’s been easy to read since. The green shows up clearly through the glass and gives me a good sense of where my CO₂ is sitting throughout the day. So far, so good. That said, one thing to note — if you’re using a CO₂ system without a built-in drop counter, this won’t replace that. You’ll still need a separate bubble counter to dial in your injection rate. The drop checker tells you what’s going on in the tank, not what you’re actually dosing, so it’s more of a confirmation tool than a control one. What I Like: • Small and low-profile • Clear and simple setup • Comes with everything needed to start • Easy to read color change Heads Up: • Doesn’t function as a drop counter — you’ll still need one if you don’t already have it Overall, it’s a solid little tool for keeping an eye on CO₂ levels. It does the job without being bulky or confusing, and at this price point, I think it’s worth it. Would recommend if you want a reliable visual check without spending a ton..

My only gripe is that the accompanying CO2 detecting liquid could have been more
