Customer Reviews
Good regulator, easy to set up
I got the Dual Stage CO2 Regulator last month. It arrived pretty quick, took about 4 days to reach my place in Texas. Hooking it up was straightforward enough, even for me who's not super technical. It's been working fine, keeping the CO2 consistent in my tank, which is what I needed. No complaints really, does what it's supposed to.
Decent kit, but slow shipping
I purchased a Complete Aquarium CO2 Kit, and for the most part, I'm satisfied. The quality of the regulator and diffuser felt pretty robust, and the instructions included were clear enough to get everything hooked up without much hassle. My plants are pearling nicely now. However, the shipping was a bit slower than I expected; it took around 8 days to get to me in California, which felt a little long compared to other online stores I use. Also, the tubing included felt a little stiff, making it tricky to route neatly in my setup. Overall, it's a solid kit for the price, but there's room for improvement on delivery speed and perhaps offering a more flexible tubing option.
Absolutely love this regulator!
I ordered the Pro-SE Series CO2 Regulator and it's fantastic! Setup was a breeze, and my plants are already looking so much better. The build quality is super solid. I'm definitely coming back for more stuff and telling all my aquarium friends!
Co2art Community Discussion
Share tips, ask questions & help fellow shoppers save more
Thinking of getting a Pro-SE, but then I saw the Pro-Elite. What's the real difference between those two regulators? Is it worth the extra cash?
Trying to use a first-time customer discount code but it's not working with a Black Friday sale item. Can I not combine them?
how's the return policy if I get a diffuser and it's not quite right for my tank? easy to send back?
Quick question about shipping times, if I order a regulator today, how long until it gets to New York City?
Anyone know if CO2Art is legit or just another drop shipper for some cheap stuff? The prices seem really good.
