Customer Reviews
Dual Stage Regulator and accessories
I ordered the Dual Stage CO2 Regulator, a CO2 Drop Checker, and some Plant Fertilizer. The ordering process on the website was pretty user-friendly, found what I needed without an issue. Delivery took about a week to my place in Ohio, which was within the expected timeframe. Everything was packaged securely, no damage at all. The regulator itself feels very solid and well-built; instructions were clear enough for setup. I had a question about the 4dKH Reference Solution – not included but recommended – so I used their online chat. Support was quick and helpful, they linked me right to it. The Drop Checker works as expected, and the fertilizer has been good for my plants. Overall, I'm satisfied with the quality and the experience.
Good deal on a complete kit
I was researching different CO2 systems for a while, trying to find the best value. Ended up getting the Complete Aquarium CO2 Kit here during a sale, which felt like a good chunk off the regular price. Shipping was free because the order was over $50, which helped a lot. It arrived in about 5 days, and setting it up was straightforward. Definitely felt like I got my money's worth.
Always a smooth order
Got another Flux_ Diffuser and some Polyurethane Tubing. It's my third order from Co2art, and as usual, everything was packed well and shipped fast. The products consistently perform, and I never have to worry about quality. My aquariums always look great.

Hey, looking to grab one of those complete CO2 kits. How long does shipping typically take to California?
Are the CO2Art regulators compatible with standard US CO2 tanks, like the ones you get filled at a welding shop?
