I have a pump for fish tank that I am going to use with hose and a stone to aerate wort, but when do I do it before or after adding water?
Depends.
Aerating is all about having healthy yeast. Yeast have a tough time in denser, high-gravity wort. If a beer is low gravity then I will just rely on splashing the wort around when I fill the primary fermenter, and maybe swirling it up after that. If it is a beer with moderate gravity wort I will use my aerator right around when I add yeast. If it is a high gravity beer I'll aerate when I add yeast, and then again around 12 to 18 hours.
Does aerating the wort after pitching the yeast effect flavors any? I would imagine aerating after pitching the yeast speeds up the process? I am letting my extract kits sit in the primary for month. I'm in no hurry.
Me, Never.
@Irishguy42 I haven't completely settled on the numbers, but in this case I'd say that I consider light gravity to be below 1.048ish, and high gravity to be above 1.075.
For me it can vary a bit depending on my mood, what the beer style is, whether it is an ale or a lager, how finicky the yeast is, or how well the starter I made looks or how well the smack-pack inflated. But I'd say that I'm never too far off from those numbers.
