Sicce CO2 Life 2 CO2 Injection System, 75gal

I have been using this system for 2 1/2 years without any problems! Anyone who knows this type of carbon system would know there are NO bubbles. It works great!!! Maybe the people who enjoy bubbles should go watch the Lawrence welk show!

I did not see any co2 bubbles coming from this unit what i did get was a big mess to clean up the filter media and my phosphate media were covered in black carbon. i would not recomend this item to any one.

I installed one of these units a couple of weeks ago in my 75-gallon tank, and it has had a transformative effect on the plant life thus far. I understand thatusing a pressurized CO2 tank is more cost effective over the long run and lends itself better to fine-tuning. But for someone who doesn't want the trouble of a more complicated set-up, this item is a terrific solution as it involves nothing more than sticking it in the tank and plugging it in.AUGUST 2013 UPDATE: Unfortunately, the product seems to have stopped functioning since I replaced cartridges.

I have attached it to the timer to produce CO2 during the day when the lights are on. I have seen the CO2 increase from almost 5ppm to 30ppm (with medium setting) in 2 weeks. I am not sure how long the cartridge will last though, I am told it will last for 3 months.

Complete waist of money! does not work. Your better off buying Seachem Flourish Exel instead or just bite the bullet and purchase an actual CO2 system

I recently purchased one I figured I give it a shot. Took a chance since review were limited. What a waste of time that was.First unit never worked kicked 3-4 bubbles and that was it. Had it replaced only to get the same results. I literally went through five units and only one worked ...for two days. Tried the Nutrafin only to get expired packs so I went all out and I ended up purchasing an Aquatek paintball regulator with solenoid and a paintball tank and the fluval diffuser and counter. Spent a bit more but no guess work.

I wish I never bought this CO2 generator. It worked for few days and then stopped. It didn't help my plants and I feel like I just waisted my money. I should have read the reviews before buying.Try something else.
