Question reactor help

I have a aqua madic co2 external reactor . I dont know where the water line should be . if i make the water fill it then the co2 fills the top of the reactor and i dont know if i am getting a good mix. the co2 slowly pushes down the water . but if i let half the reactor fill does the co2 that fills the top of the reactor mix in with the water ?

Yeah, the CO2 enters at the top on those reactors and the turbulence and bio balls will churn up and absorb the gas. There is no "water line". Its an inline reactor powered either by an in-tank pump or a cannister filter's outtake. Do you have a bubble counter with the set up? If not, Aquamedic makes a decent one for about $20.00. You will need to check your pH and KH to determine your level of CO2 dissolved in the water. Around pH 6.6 and KH 4 will give you around 30ppm which is a fairly desireble level. Here is a link to a chart.

The water first enters the reactor at the top and exits at the bottom. You do have it plumbed that way, right? You can see a picture of it plumbed such at Drs. Foster and Smith's website. HTH

If ur powering it via a seperate pump like I am, then you wanna shoot for no less than 300gph or you'll never get rid of that "water line".
