Most of the radioactivity was from Iodine, which has a half life of about 9 days, so besides being diluted in millions of liters of water, it looses about half its radioactivity every 9 days.
Also the impact on marine life is almost nonexistent, since the area it was poured in, was already struck by a tsunami that ravaged everything there and scattered the fauna away.

Without day-to-day monitoring of sea contamination it's too early to speak about completely safe situation.
