Hello AeroPro, I am new to this site and would like to ask you a question. Do you have an AeroFlo2? I only ask this because I just built my own. I copied it from the GenHydro site. I would have bought one but needed to save some cash. My real question is if you happen to own or have owned one... How exactly do they attach the laser line on the inside of the tubes? Are they just laying in there? or are the suspended above the nut chamber? I would assume suspended, but totally confused on how to attach the lines. Please Help, Please. OIO
