Not long. It should be used immediately after aeration stops. You shouldn't aerate it for more than 48 hours or so because the air-stones will clog up with bio-slime and it will still go anaerobic eventually. Use it within a few hours at least.
I've heard it can be refrigerated to prolong the life of it but it's really best to use it as soon as possible and just make up another batch the day or night before you plan to\have time to use it. You can apply it as frequently as you'd like (within reason), every week, every other week, once a month, whatever.
