    I am somewhat confused on this setup. the mazzei sucks so hard that when I have the co2 on, the mazzei sucks from the o2 and co2 line simultaneously mixing o2 with co2. the only way i can keep this from happening is reversing the check valve on the o2 line keeping anything from entering the o2 tube. does an air pump have restriction from o2 getting sucked from it? how do you keep the o2 from leaking when the co2 is on?

    this is my setup (please ignore the dots i had to add it because my diagram got all scrunched up and un-legible when i tried to post it using spaces)

    I keep them(CO2 and O2) entire independent and separate.

    jazz,

    I THINK that:

    the 02 air pump is not on when the c02 is.......the check valve on the o2 line will keep c02 from entering/exiting the pump,

    I think your plumbing is good in your pictogram. 02 and c02 are on separate timers so they are not on at the same time...

    co2 does not back up into the air pump however the suction on the mazzei is so great that o2 keeps injecting in the mazzei when the even when co2 is on. I don't want o2 to mix with the co2 when lights are on and I think my only resolution to that is a 2nd solenoid
