Customer Reviews
PRO-Elite regulator and CO2 cylinder
I ordered the PRO-Elite Series Dual Stage Regulator and a CO2 Cylinder because my old setup was leaking. The unboxing was good, everything felt solid. Shipping took about a week and a half which was okay coming from overseas. The regulator itself was easy to set up with the instructions, and I appreciated the detailed warranty info on their site. My plants are pearling nicely now. I had a quick question about the solenoid valve and their support got back to me the next day, which was helpful. Overall, a good experience.
Good diffuser, shipped fast
I grabbed a Flux_ Diffuser for my 10-gallon tank last week. It got here pretty quick, like 5 days to reach me in California. It works well, seems to make small bubbles. Happy with it so far.

quick question: saw a youtube video of an aquascaper using a 10% off code for CO2Art. are those still floating around? or do I wait for black friday?
hey, was looking at the pro elite regulator, are those things really that much better than like, a fluval or something?
