Customer Reviews
Detailed review of CO2ONE Regulator
I ordered the CO2ONE Universal CO2 Regulator, along with a CO2 Bubble Counter and CO2 Drop Checker. The ordering process was smooth, and I received a confirmation email immediately. Shipping took about 6 business days to reach my address in Texas. Packaging was excellent, with each component individually wrapped and protected. The regulator itself is robust, and the precision needle valve allows for very fine adjustments, which is crucial for a planted tank. Installation was fairly simple following their online guide. I had a quick question about the solenoid valve connection, and their online chat support was responsive and gave a clear answer within minutes. The quality seems comparable to more expensive brands I've used.
Good value on fertilizer
I was looking for some new Aquarium Plant Fertilizer and Liquid Carbon Supplement. I compared prices with a few other places and Abcplants had a pretty competitive deal, especially with the free shipping on orders over $100. The products came well-sealed and seem to be doing the trick for my plants. It felt like a solid purchase for the money.
Good system, slow shipping
I bought the CO2ONE Complete CO2 System a few weeks ago. The system itself works really well; my plants are bubbling nicely. Setup was pretty straightforward with the provided instructions. My only gripe is that it took 8 days to arrive, which felt a bit long compared to other online stores. Customer service was helpful when I inquired about the delay, though.
Reliable for my tanks
This is my third order from Abcplants, I picked up a new CO2 Diffuser and some Glass Lily Pipes. Like my previous CO2ONE Nano CO2 System, everything was packaged securely and arrived in perfect condition. It's consistent quality and I know what to expect. Good to see they're still doing things right. Will be back for more.
Love my new lights!
I got the Aquarium LED Lighting and it's fantastic! My plants are looking so much healthier already, and the tank just sparkles. It was super easy to set up and looks really sleek. I'm so glad I finally upgraded. Definitely shopping here again!
Got my Aquascaping Tool Kit
Just received my Aquascaping Tool Kit. I really liked it, all the tools felt solid and worked great for trimming my plants. The curved tweezers are super handy. The website was easy to use too, so no complaints there. Pretty happy with it.

Do these CO2 systems work with paintball tanks? Or do I need to get a specific CO2 cylinder for them?
Hey, thinking about grabbing a CO2ONE system. How's the shipping usually? I live in Seattle, WA.
