Customer Reviews
Consistent quality, great service
This was my third order from CO2Art, and as usual, everything was perfect. I picked up some more CO2 Resistant Tubing and a few O-Rings this time. Their products are always top-notch and reliable. My first PRO-SE regulator from them is still running strong after a year, and I appreciate that the quality hasn't dropped. It's why I keep coming back.
Detailed feedback on my order
I placed an order for the PRO-SE Series Dual Stage Regulator, a Precision CO2 Bubble Counter, and an In-Line CO2 Diffuser. The ordering process on the website was straightforward, and I received an order confirmation almost instantly. Shipping took 8 days to reach my address in Florida, which was within the expected timeframe stated on their site. Packaging was excellent; everything was securely nestled in foam, preventing any damage to the glassware. Installation of the regulator was intuitive, and the instructions were clear. The diffuser works effectively, and the bubble counter helps fine-tune CO2 levels. I had a quick question about threading for my CO2 cylinder, and customer support responded via email within 24 hours with a helpful answer. The build quality of all components feels robust, offering good value for the price.
PRO-Elite is fantastic!
Just received my PRO-Elite Series Dual Stage Regulator and it's incredible! Installation was a breeze and my plants are already pearling like crazy. The build quality is superb. I'm so happy I finally upgraded. I'll definitely be buying more stuff here, probably some new Lily Pipes next!
Fast shipping, good products
Ordered a Magnetic Glass Cleaner and a Digital Thermometer. Shipped fast, arrived in good condition. Products work as expected. No complaints. Would buy again for sure.
Mostly good, minor issue
I purchased the PRO-Elite Series Dual Stage Regulator and some Aquascaping Tweezers. The regulator itself is excellent, very precise, and feels well-made; it's a significant upgrade. Shipping was reasonably quick, about 6 days to get to me in Texas. My only minor gripe was that the tweezers felt a bit lighter than I expected for the price, not quite as robust as other tools I own. They still do the job, but it was just a small detail. Customer service was responsive when I inquired about tracking. Overall, a positive experience, but the tweezers could be improved.
CO2Art Community Discussion
Share tips, ask questions & help fellow shoppers save more
Are the CO2Art regulators compatible with standard US CO2 cylinders, like from a local gas supply store?
Hey, anyone know if CO2Art ships to the US? Like, is it a pain or do they handle customs okay?
Anyone compared the CO2Art regulators to something like a Fluval setup? Is the price difference worth it for CO2Art?
Thinking of grabbing the PRO-Elite regulator, but kinda pricey. Do they ever do sales on those or have discount codes floating around?
How long does it usually take to get stuff from CO2Art if I'm in, say, California? Need a new diffuser kinda soon.
I'm looking to buy a bunch of stuff - regulator, diffuser, some tools. Can I stack a couple of discount codes for a bigger saving?
What's the deal with returns? If I get a diffuser and it's not what I expected, can I send it back, even if I've opened it?
