This CO2 system was super easy to set up for my 10gal planted shrimp tank. I've had no issues with leaks, balancing CO2 output, or anything else a couple reviews mentioned. Just pay attention to the instructions and use a bit of logical thinking and you'll be fine. I haven't run out of CO2 yet, and it's been up for a few weeks. Needle hasn't moved much, which makes sense as I have it set to approx. 2 bubbles per minute, which seems to suit the plants and shrimp just fine. Very reasonably priced as well. I will certainly consider buying this system again in the future for smaller tanks!

Easy to use can use wide range of co2 canister from 16g to 45g with different attachment made for it, no leaks been running it for 8 hours a day my plants are thriving.

This is great! I have tried different ones before like fluval. It was okay but this allows for much better regulation on the bubble count which is essential. It exceeded my expectations and very easy to set up. Looks nice and sleek as well so it doesn’t look out of place.

This little thing is great! Very simple to install, simple to use, diffuser leaves very fine micro bubbles. The tubing was kinked and it was a little annoying, but it was easy to fix. Love this little kit and will be purchasing for all my future nano aquariums!

I have been using it for over a few months now and my plants are flourishing. Highly recommend and it's small and compact.

Great tool to have. Works really well and instructions were very clear. I was wondering if they make a solenoid DC valve for this model like Fzone does? I liked that this brand included the diffuser and the tubing. Both of which work great for diffusing my bubbles evenly.

This is the first time I've used pressurized CO2. I was looking at the FZONE desktop setup, but delivery was weeks longer so I went with this hygger setup even though there were no reviews and no returns. Yeah, not smart, but I was rewarded. This is a great system. The metal parts are sturdy, the valves seal properly, everything is easy to connect. The instructions were very clear. I was pleased to see when I went to connect the canister that there is already a white gasket in the regulator, as well as the one included in the accessories bag. Nice to have a backup for the one I'll use most. I found it easy to get the flow down to .5 BPS, and easy to adjust up to 1 BPS (7 gallon tank). One thing I liked over the FZONE was that this hygger set includes a diffuser, hose, and suction cups as well as adapters for 5/8" canisters. To me this makes up for the higher cost compared to FZONE, as I would have had to buy those things. Cons: the price is higher than the FZONE the screw on base is slightly off when connecting to the regulator, see photo the included airhose is kinked, I had to fiddle with it to get straight hose no check valve included Pros: diffuser, hose, suction cups included extra 3/8" gasket sturdy, stable, not easily knocked over all connections seal tightly, no sign of leaks valve easy to control looks great next to my tank (kids and husband have all said "it looks really cool") I recommend this set if you have a small tank and want to use CO2.
