For the third time, I plan to remove this strip of caulk in my bathtub/shower a bit beyond the discoloration (mold?) and recaulk it. I would like to get it right this time.
I plan to remove the caulk where it is discolored (mold?), clean it, let it dry for 24 hrs, and recaulk using Loctite Polyseamseal Tub & Tile, then let it sit 24hrs before use.
What else should I do to ensure this discoloration (mold?) under/in the caulk doesn't return? I thought I did it right last time, but obviously I didn't.
Also, is this the right sealant for this job?

Isherwood's right & make sure you're actually getting the blowing air from the bath fan on the outside of the house. Also, after showers or baths get into the practice of letting the fan run for another 15 or 30-minutes.
You just want to fill, actually fill, that crack below the tile is all. Squirt caulk INTO the gap & then force more caulk into the crack with your finger or a putty knife & repeat until it's full. Your closed palm should be facing the wall & not down toward the tub.
There's no need nor benefit in trying to make a ramp for the water. Water sitting on the caulk rather than beside it is mold's friend. Your caulk should look largely like your grout lines, it should be thin, tight & flush with the tile face.
