This is a weird question, right, but I'm setting up the 180l at the moment with a 1200lph filter and pressurised CO[sub]2[/sub]. Since I'm going to be using an external atomiser and external heater, I'm wondering which should come first on the way out of the filter? I was thinking the CO[sub]2[/sub] so that it gets longer to dissolve in the water as it passes through the heater and stuff, but I dunno if it really matters?
Does it?
