the first and most important step would be for you to get your ears properly examined. if you do have a full or partial wax impaction (trapping water behind it) or if wax or other debris is touching your eardrum this can be seen on examination and corrected on the spot in most cases. however if the crackling is caused by fluid or pressure variations in your middle ear space (the area on the other side of your eardrum) then the treatment would be different and perhaps take longer to achieve relief. swimming in water that may not be cure can lead to otitis externa (swimmer's ear) but this condition tends to be painful. crackling would not be your only symptom. as you may know each time you swallow air goes up your eustachian tubes to help equalize pressure. this is a normal response that goes on hundred of times every day. if you have fluid in your middle ear space (it is supposed to be just air) this can create little bubbles and those bubbles can cause crackling sounds sometimes. again an ear examination should be able to determine if you have middle ear fluid. treatment of any fluid would depend on the amount of fluid and how long you have had this condition . treatment options are very individualized range from using nasal corticosteroid sprays to having tubes inserted by an ent.
