Abyss is an underwater shaderpack built around the atmosphere of the deep ocean.

Light fades quickly, colors disappear with distance, and most of the world is only visible through your lamp or the things glowing around you. The shader includes underwater light absorption, bioluminescent patches, marine snow, backscatter, glow, and several presets for different deep-sea environments.
You can adjust the water, lamp, bioluminescence, marine snow, and post processing directly from the shader settings.
