I have a 180g planted, and I am gonna start using this and dont want to be buying those little bottles every few weeks. So, anyone know where to get large quantities for cheap.
 
get a pressurized or DIY CO2 system?
I already have automatic pressurized with controller. I am just trying to gain some form of control over algae, and from what Ive gathered it can still be used in conjunction with co2.:read:
 
Been getting mine from Doctors F&S for $20 for a 2 liter jug.
