This was briefly used in our aquarium setup. We have since switched to a pressurized gas system to work with multiple tanks. We don’t have the original box for this, but it comes with all the pieces that you will need to get started with your own planted aquarium setup.

Parts included:
* Stainless-Steel Reaction Chamber
* Sure-Lock clamping cover
* Adjustable bubble counter with precision regulator
* 12V Solenoid Valve with power supply (will need a timer or app-controlled outlet)
* Nano Bubble Diffuser (the stone diffuser is cracked and has been repaired, but buyer can always get a new one)
* Pressure Release Valve
* Inline Check Valve
* Gasket
* Airline

You can purchase Fluval’s refill packs, or we found it more cost effective to just make our own yeast/sugar mixture at home. There’s various recipes online for that option. Either way, this low pressure system is great for those that don’t want to deal with pressurized gas or can’t find a refill location nearby.
