Customer Reviews
Good diffuser, fast shipping
Ordered an Inline CO2 Diffuser. Shipped quickly. Arrived in good condition. Works well for my tank. Happy with the purchase.
Easy setup, looks good
So I finally got around to getting some CO2 for my planted tank. Picked up the Flux_ Diffuser and it's pretty neat. My old one was just a plain glass one, this one looks way better in the tank. Setup was quick, just popped it in. The bubbles are super fine which is what I wanted. Definitely makes a difference for the plants. Glad I got it.
Pro-SE regulator review
I ordered the Pro-SE Series CO2 Regulator. The ordering process was straightforward on their website. It shipped out fairly quickly, took about 4 days to reach me in California. Packaging was solid, everything arrived intact. The regulator itself feels very well built and sturdy, not flimsy at all. Installation was easy enough following the included instructions. I connected it to my tank without any issues. The bubble counter is precise, and I haven't noticed any leaks. It's been running consistently for a couple of weeks now. Customer support wasn't needed, which is always good.
Good value for a complete kit
I was looking for a CO2 setup that wouldn't break the bank and found their Complete Aquarium CO2 Kit. Compared to other places, this seemed like a really good deal. I managed to snag it during a sale, which helped even more. Shipping was free because the order was over 50 bucks, so that was a plus. Overall, I feel like I got a lot of bang for my buck with this purchase. It felt worth it.
Consistent quality, returning customer
This isn't my first purchase from CO2Art. I've bought a few things over the years, including my original Pro-Elite Series CO2 Regulator. This time I needed some Replacement Washers and a new Check Valve. Just like before, the order was processed fast and arrived in good time. The quality of these smaller parts is just as good as their main equipment. Everything fits perfectly, no surprises. It's why I keep coming back; I know what to expect and they deliver.
Co2art Community Discussion
Share tips, ask questions & help fellow shoppers save more
Hey, thinking about grabbing a Pro-SE kit. Does anyone know if their regulators work with standard CO2 tanks you get from a welding supply or something similar?
Does co2art usually have any sales around Black Friday or Cyber Monday? Planning a big order and want to save some cash.
Are the Pro-Elite regulators really worth the extra money over the Pro-SE? Trying to decide which one to get for my new 75-gallon.
I'm in Los Angeles, how long does shipping usually take for a complete kit? Need it somewhat fast for a new setup.
