After some in-game testing...

Hold 4 for 2 seconds to double the range. You can also grab enemies from outside the pool while sitting in Undertow, then cast Tentacle Swarm. Tentacles can now hold multiple enemies as well. It's like Nidus' Larva but done manually and in a combo with abilities.

Blow them all up with an AoE weapon and you have yourself tons of loot neatly piled up where you want.
