CO2 made simple for the first time user
I'm a first time CO2 user and this is my second venture into the aquarium hobby. My first go round, I always wanted an nice lush planted tank but I was in my early teens and couldn't afford the size tank or the items required for that kind of setup.Now on my second go round, I decided to follow that path of my dream aquarium and with that came the initially overwhelming prospect of CO2 systems.The Fzone CO2 generator system has made that very simple and significantly less daunting for me. It comes with almost everything that you need to set up the system. The only things the system doesn't come with is sodium bicarbonate, citric acid, a digital scale, or check valves. I highly recommend you spend a couple dollars on check valves. Those check valves will keep water from backflowing into the co2 lines when you have the system off. If you want to make your life super simple, you will need them. They also allow you to easily disconnect the bubble checker when it comes time to refill the bottle with your baking soda and citric acid.Now, I did say I'm new to CO2 so I did make a mistake when filling the bottle. The directions specifically state to hold the bottle at a 45 degree angle when filling. I did this until I went to grab the cap. When I reached for the cap of the tank I set the canister straight up, which meant I ended up having a fountain of the chemical reaction shoot out of the top of the tank until I was able to screw the cap onto it. Don't make the same mistake I made. That was my own mistake I made, like I said I knew it had to be held at an angle and I had an airheaded moment.Now I will say, if you have a larger tank, go for the 5L kit. I have a 75 gallon and I have had the CO2 on a timer, and my tank pressure has gone from 400+ PSI when freshly full to 150 PSI in 4 days. I will most likely need to upgrade to the 5L bottle here in the next month or so, but I also have my system running for 11hrs a day.As stated, the tank pressure goes up to over 400PSI, which already tells me that the build quality is quite superb, and I noticed some other reviews state that the knob to adjust the bubble flow was a bit touchy. My specific system was just touchy enough to where it was actually pretty easy to set my flow rate at 3 bubbles a second without really struggling with having to fiddle around with it. The tank is pretty weighty, but I believe that's due to the fact that it is built very well. When you initially fill the tank it will get cold enough to condensate on the outside, but that is due to the chemical reaction. It's not a flaw.Overall the 2.5L was perfect for me to dip my toes into the beautiful world of planted tanks, and is good value for people who have a smaller setup, such as a 29G or less. For my specific use case, I will need the 5L so I don't have to refill every week.

Excellent Product, but.....
The media could not be loaded. Just received the product this afternoon and got it up and running. At last look it is charged with about 410 psi CO2 and 60 PSI in the can, which is good. I am very happy over all with the product, but I do want to point out some serious issues with the written directions included with the system. I think they are really bad because it does not even address how to hook up the Solenoid. I figured out by intuition. The really big mistake in the instructions is the wrong material weights and water volume to mix together in the tank. That mistake cost me $16 in citric acid and sodium bicarbonate material. I had to depressurize the cylinder and empty the contents and start over. That was really bad. I have included pics of the instruction sheet and the label on top of the cylinder in yellow, which does not match steps 1 and 2 in the instructions. Also, I did end up breaking the curved glass CO2 hose connector that hangs over the rim of the tank trying to assemble it. The adjustable valve that releases C02 into the bubble counter is very very very touchy and hard to dial in because it is tight to turn and the slightest adjustment once it is open and gas is flowing will exponentially alter the bubble rate. Not a fan of the adjustable valve because it is so difficult to dial in. I tried to time 1 bbl per sec but could not exactly dial it in. Close enough I guess. Over all, for the price and what it achieves it is a good product and I do recommend it. I plan to keep it for at least 90 days to see how it performs. If I end up being dissatisfied with the system, which I do not anticipate at this point in time, I will purchase a 10LB CO2 tank from Airgas nearby and get CO2 refills going forward for about $30. I also purchased the Milwaukee 122 PH controller at Amazon to mitigate any harmful PH changes in the aquarium. It will shut off the solenoid power on the CO2 tank if the PH drops below my desired limit. Pretty cool setup over all for a relative low cost CO2 system and I'm pretty excited about it. Hope this info helps. 60 day update: refilling the cylinder because it was close to being in the Red on the C02 gauge. However, there is an issue with the PSI tank gauge. It is stuck at 50PSI but, the regulator is not even connected to the tank. I disassembled it to add the new ingredients. I tried tapping on the glass PSI gauge to get it unstuck to no avail. And of course its past the 30 day return period. See added picture.

4L Tank - Perfect for larger aquariums
The media could not be loaded. Excellent product. For years I have struggled to maintain a co2 consistently due to issues with local supply.Using a recipe of 600g citric acid, 786 g baking soda, and 900ml of distilled water I am consistently holding 52 PSI with the tank holding in the green. The solenoid works perfectly, simply screw it in between the regulator and the bubble counter and plug it into a timer.This system also ramps up quickly once turned on, typically it takes a while for the BPS to come up, but this one is at full speed within a matter of minutes.My plants are loving the new addition to the tank, and I will be adding significantly more soon.I am running an 18 hour automated photo-period light with the co2 system running to an inline diffuser that runs through the spray bar.I recommend using a calculator online to determine the approximate BPS required for your tank based on your PH, KH, plant density and tank size.

It's cheap.
Set up in June, and it's been a headache. I have had to replace the solenoid valve. I have it set with a timer, and after some time the co2 and bubbler wouldn't turn on. I had to manually turn on co2, and adjust throughout the day, everyday. If I didn't do this, the co2 would slowly shut off. Due to the instability in the tank, I have fought with algae most of these months, leaving my plants became susceptible. Replacing plants became an investment as well. Please do yourself a favor and invest in something better than this cheaply manufactured product.
