Color: 2L with Dual Gauge
I'm very pleased with this system. It's a good alternative to pressurised CO2. The instructions are very clear with photos showing every step of the installation. The only time I experienced an issue was getting the pressure dialed in correctly. When I plugged it in for the first time, the bubble counter valve was fully open causing all the water from the bubble counter to blast up the airline, so I had to stop, refill the bubble counter & then it took me another 20 mins to realize this had also cracked the check valve so the co2 was leaking out before making it into the aquarium. So for the time being, I just removed the check valve altogether until I could get another & just detached the hose completely at the end of each day to prevent any siphoning. But once I figured out how to operate both pressure guages & got my count dialed in, it has since been an absolute breeze to operate. I would recommend to check & make sure the bubble counter valve is completely closed before plugging in & one the recommended pressure is reached, very slowly open it to achieve the count u want. The top valve controls how much pressure is on the entire system, so u can quickly open it to release any pressure if the guage begins reading in the red. I've never needed to do that, but I have had to tighten it a few times over the past month due to loss in pressure. It all sounds so much more complicated than it actually is, I promise. I just exhausted my first round of mixture & it lasted me about 40 days at 2-3 bps on a 30 gallon rimless aquarium. I noticed a difference in my plants within just a few days of running the co2. They're growing beautifully & the pearling alone just makes it totally worth it. I've also experienced a noticeable decrease in algae. Bottom line, I think this is a phenomenal alternative to the more expensive systems out there. I also really like the clean sleek look of this stainless steel system on my tank. I later purchased a ss check valve to match it & replaced the included diffuser with a glass diffuser. I also installed a glass drop checker on the opposite side of the aquarium to keep on top of how much co2 is in the water. The whole set up just looks really nice & high end. I connected it to a smart outlet, so I can turn the system on & off with my phone, & I currently have it automated turn on an 90 mins before the lights come on in the morning & shut off 2 hours before the lights go off in the evening. Like I said, once u get it all set, it's a breeze. I would absolutely highly recommend this to anyone wanting an easy, affordable way to run co2 on a planted aquarium. Just check the pressure guages every so often bc they will fluctuate as the mixture is exhausted & enjoy the beautiful pearling plants you'll be growing! **10mo. Update: System still operating fantastically. I've since moved up to a 50gal rimless aquarium & have to refill the mixture about every 3-4 weeks set @ 2bps. It operates so efficiently that I was actually forgetting to check when the mixture's exhausted & needs to be refilled. So I set a reminder on my phone that notifies me every 4wks to check the system, it takes me less than 10 mins to rinse, refill & reconnect it. I've replaced the diffuser once again to a more efficient type, but plan to upgrade to an inline diffuser soon for an even cleaner look. I highly, highly recommend this DIY CO2 setup. Couldn't be more pleased with the look & the results. Will be ordering a second one for my other aquarium when I can afford to.

Color: 2L-New upgrade
So far, I like this device and it is super sturdy and looks seriously tech. It really turned out well and was very easy to install. I used the instructions for the dose of chemicals needed, but used the video here on Amazon to get everything connected right. I don't know how many CO2 bubbles I need, but I got it running. You may need a short extension cord which I did as I didn't have it close to a plug outlet. It's a two prong for those of you who want to know. I got it up to the psi that it said and then started putting everything on it like the video showed. I was a little paranoid about cutting the plastic hose air cord but then finally just chose my location which was at the back and figured out where I'd put the in between piece. FYI - the steal curve to hang the plastic didn't work on my tank as it's a black rim 120 gallon and too thick. Luckily, the bubbler piece is heavy so I didn't need it. Oh, make sure the bubbler piece is screwed on snug unless you want a giant bubble which I corrected.. Note - do not put it near an intake as it will fill up your filter with air! I have it on the end with my out take of my canister filter. Fish aren't disturbed by it. I needed CO2 for my plants as I'm getting a lot of algae and my plants needed a kick to grow better. I didn't want to fuss with gas. I admit that my first try sorta failed. I don't know if I mounted the top part with the gasket wrong but it [the gasket] popped out. I lost all of my gas from the first batch and tried again [so buy yourself some big bags of the chemicals or you'll hate yourself and get frustrated], but I used one of the spare gaskets in case the other one was a little odd to try the second time. It's now working perfectly! I am running a serious bubbler with air so that when my lights turn off I don't accidentally hurt my fish. I read that can happen. So far, so good. Once my plants are seriously growing I'll try posting a picture here to show the end results.

Color: 2L-New upgrade
Received the package, all parts looks well made. The installation is easier than I thought. Got over 200psi after one night reaction and whole system works well at the 1st day. Next day morning when I check found some water inside the air tubing, clear out the water and turn on the system but no bubble comes out from atomizer. Tried replace with the space atomizer tablet but air leaking from the tablet bottom. Not sure why and really disappointed, will return if the seller can't help me fix it. Updated on 1 week later, seller responds in 2 days via amazon service and most important problem solved! back to 4 star. The reason why take one out is the space atomizer still not working.
