Customer Reviews
Consistent quality, again
This was my third order from CO2Art, this time I picked up some Glass Lily Pipes and a Surface Skimmer. Like my previous purchases (a regulator and some tools), the quality is consistently excellent. The glasswork is flawless, and it arrived without a scratch. Shipping speed was about the same as before, around 8 days to Florida. It's why I keep coming back; I know what to expect, and they always deliver reliable, good-looking products for my planted tank.
Good diffuser
Got an In-Line CO2 Diffuser. It shipped fast. Works as it should. No issues. Very good quality for the price.
Regulator and accessories
I ordered the PRO-Elite Series Dual Stage Regulator along with a Flux_ Diffuser and some CO2 Resistant Tubing. The ordering process was straightforward on their website; I found everything easily enough. Delivery took about 9 days to reach me in Texas, which was pretty much what I expected coming from the EU. Everything was packaged really well, no damage at all. The regulator itself feels very sturdy and high quality, much better than my old one. Installation was easy, the instructions were clear. The diffuser works great, very fine bubbles, and no leaks from the tubing. I had a quick question about setting the bubble counter for my tank size, and their customer support replied to my email within 24 hours with a helpful explanation. Overall, a solid experience and good products.
Got my CO2 Drop Checker
So I needed a new CO2 Drop Checker because my old one broke. Found one here, it was super easy to order. Came in like a week, which was cool. Looks nice in the tank, does what it's supposed to. No complaints, felt good buying from them.
CO2 Cylinder and some supplements
I bought a CO2 Cylinder and some Plant Fertilizer and Trace Elements. The cylinder arrived full and well-packed, which was a relief. Shipping did take about 10 days, a bit longer than I hoped, but I understand it's international. The supplements seem effective, my plants are pearling nicely. My only minor gripe was that the tracking update wasn't super detailed for a few days in the middle of transit, so I wasn't sure exactly where it was. But everything arrived safely, and the product quality is high, so I'm mostly happy with the purchase.
Great value on the PRO-SE
I was looking for a good deal on a CO2 system and saw the PRO-SE Series Dual Stage Regulator here. The price was really competitive, especially compared to other places I checked. It felt like a solid investment without breaking the bank. Shipping wasn't instant, took maybe 7-8 days, but it was free for my order which helped save some extra cash. Everything arrived safely and works perfectly. Definitely felt like I got good value for my money.

Share tips, ask questions & help fellow shoppers save more
Curious about return policy. What if I get a diffuser and it's not the right size for my tank or something? Is it a pain to send stuff back?
Are there any current discount codes floating around? Planning a big setup and trying to save some cash.
Do their regulators work with standard fire extinguisher CO2 tanks? Or do you need special cylinders?
Anyone know if they ship to the US? Really want to snag one of their diffusers but not sure if it'll even make it across the pond.
Hey guys, thinking of getting the PRO-Elite regulator. Are these things really worth the price tag? Like, compared to other brands, is it a noticeable step up?
