Add 1 - 2 gallons of bleach every evening, till full. If you detect the slightest bit of 'green' while filling, add 4 gallons. Begin running your pump and filter, as soon as you can prime the pump, but not till the bottom of the pool is covered in water. (You don't want a jet of water hitting the pool surface directly -- depending in your water, doing so can result in stains and/or erosion.)

Likewise, avoid having fresh fill water come into direct contact with the pool surface. If there's any reason to suspect metals (iron?) are present in the fill water, add a liquid stain / scale treatment as you fill -- do NOT over dose. Dose for the water present; not for the what will be present when the pool is full.
