Welcome! Yup, we need to know more. You will need either someone or something to make sure chlorine levels stay up.
Without knowing more, this is NOT a suggestion but an example. When we would travel, I would have someone pour a gallon of bleach in every other day and always came back to a clean pool, even after 2 weeks of this treatment. The bleach would keep the pool clean and everything else would stay in balance.

There are at least 4 other ideas I can think of, when we know more.
