Aloha nui loa, Aloha nui, or Aloha no. Nui means big or grand, and loa and one usage of the word "no" are intensifiers that makes anything that comes before even bigger. So at various times you could say, "Aloha nui," a shortened form of "much aloha," or the full "aloha nui loa," for the most amount of aloha. "Aloha no" is a common casual form, usually a greeting, an affirmation of strong aloha. This is different however from saying, "I love you," which is translated as, "Aloha au 'ia 'oe," or "Aloha from me to you."
