As a stay-at-home parent in San Diego, I'm always looking for ways to keep my hobbies manageable, and my aquarium is my little escape. I got into this because I love tinkering with things, kind of like how I handle car stuff—precision matters. When I first set up the SURTOP checker, I was a bit skeptical, but it delivered right away. It made monitoring the CO2 levels feel effortless, and I didn't have to stress over chemistry or mess anything up. Over the past couple of weeks, it's become a trusted part of my routine; I just pop it in, check the reading, and adjust as needed. My plants have never looked better, and it's brought a lot of peace to my daily life. It's quite the game-changer for anyone who wants their tank to be perfect without the hassle.
- Pros: This thing is just what I needed—it gives spot-on readings every time, so I never have to guess about the CO2 levels. It's super tiny and slips right into my tank without taking up any space, and it's so easy to use that I felt like a pro from the start. My plants are thriving now, and it's quite a relief to see my aquatic friends doing so well.
- Cons: Honestly, I can't think of any downsides. It worked perfectly as it seemed to me from day one, with no issues at all. Maybe if I had to nitpick, it's almost too simple, but that's not really a con—it's just so straightforward that there's nothing to complain about.
