Is your pool 42" or 48" tall? Your first post says one thing and your sig says another. 42" tall = 3357 gallons, 48" tall = 3861 gallons. These are approximations from Intex, but might give you better figures in the pool calculator. Two pounds of stabilizer may be all you need, so if you only have 1 pound left in the container, I would certainly think about removing some from the sock.
