My dual calcium reactor questions..

[rz1a]

okay so the seller says that it should already have the rings in the co2 regulator. so the small one is in there, im not sure if the other one was connected to the tank, but i already took the tank to get it filled up and didnt check to see. he said that what i have are extras.

also said that i should setup the reactor now without co2 and get familiar with it--- that it needs to run 24hrs to expell all the air out of it before running co2 through it
