Have you ever thought the oceans were boring in minecraft? Now they aren't it anymore. This modpack has nearly 200 mods to expand oceans with new fishes, biomes and new structures. There are even new dungeons to explore and ships to conquer. You can also discover two new water based Dimensions from Atlantis and Tropicraft.

For shaders I recommend Oceano Shaders
