Better to add liquid bleach to the skimmer or infront of the pool return?

What's the best way to add liquid bleach (liquid chlorine) to the pool water? 25k gallon in-ground pool, rectangular shape.

Always pour bleach slowly near the return jets so it can mix with water coming back to the pool. Almost never add anything directly to the skimmer. Most chemicals are too strong to get sucked-in so close to the pump.
