OK forum members, I'm in Michigan and I need recommendations on when to start up the pond maintenance activity. Our winter was pretty cold, and as of today, snow is still on the ground, but in Michigan, that can charge quickly. Specifically, when to start up the aeration pumps, I usually use Aquashade, when? I also want to do the bioaugmentation. I started in the middle of last season, and I really saw so remarkable improvements with aeration. So what's the time table for us northern boys?

Thanks
