Wonderful product for small tanks. Biggest pro was custom service. I communicated with Fzone via their Instagram but they guided me on what to buy and even helped with set up. I am sure I will have more questions. I just wish it came with a bit more thorough set up/instructions. YouTube helped in that department. Last thing is it’s not ready to go. You do need to buy a diffuser and tubing. This product would be perfect if it was truly all in one item. I did buy the Solenoid to use a timer for. The last picture is everything needed to start it going. I did then buy a U shape tube to better fit the tank.

The small footprint works great for a 5 gallon tank and cabinet! The solenoid works great with a timer. I'm hoping to get 3-4 weeks out of the canister at 1 bubble per second.
