The Carbo Bio Style 120 has made a big difference in my planted tank. My plants are growing steadily and the colors are much brighter. The stainless steel chamber is durable and the CO2 supply lasts about 40 days as advertised. Easy to refill and the pressure valve works well.

I’ve used this reactor for three months now and it’s been very reliable. The plants have grown stronger and the water looks more natural. The only thing is the initial setup took a bit of time to adjust the CO2 flow.

Great product for maintaining a healthy planted tank. The CO2 is consistent and the stainless steel build feels solid. I didn’t have any leaks or pressure issues during use. My anubias and java ferns are thriving.
