Very easy to hook up
The reactor gets fed ,from the bottom john guest connection on the pump.
The top JG connection on the bubble counter is where you inject the CO2,with this design the bubble counter fills up itself so you don't need to fill it like some other designs.
The JG connection on the second chamber is the effluent exit ,you use a
1/4" tubing to take it back to the tank.
the needle valve ,will regulate the flow of effluent exiting the reactor.
Keep in mind that there are 2 sponge pads in each chamber ,you need only 1 in the bottom of the chamber & you pour the media on the top of the sponge,the second sets ,are extra replacement for future.
You could use a set of plyers to tighten those screws or we can get the other type of screws from the store you bought it from & they could be tighten with a flat head screw driver.
The blue rings on JG connections are locks & if you need to take the tube out to put media in you remove the lock push the moving part of the connection in& gently remove the tube & open the chambers.
The probe holder is very easy to work with as well.
A few things I recomend
1- rinse media very well & preferly soak in RO water overnight
2- remove the tube from the needle valve to let the chamber fill & empty all air from it then push the tube back in & let the second chamber fill.
3- this design comes with a seated O-ring make sure the oring is in place ,you can use a little bit of silicone lubricant if you like & thighten the screws well.
You are set ,enjoy your rector
