Best run with liveaboard or local operator guidance because the channel current depends on tide windows.
Liveaboard transit dive in the Sagewin Strait; the tide window matters because the channel can run fast even when the bottom looks calm.
About Algae Patch 1
Algae Patch 1 is a Batanta muck dive in the Sagewin Strait, where liveaboards slot in tide-timed dives between Raja Ampat and Sorong. The bottom is mostly sand and rubble with coral blocks and patchy reef growth, so the real draw is close-up macro hunting rather than wide-angle scenery. Plan it with a guide who can choose the right tide window for nudibranchs, rhinopias, scorpionfish, mimic octopus, wonderpus, and other critters.
