The Council may determine the annual salary of Councilmembers by an ordinance requiring the affirmative vote of 5 (five) members, but no ordinance increasing such salary shall become effective until the next regular election, provided that such election follows the adoption of such ordinance by at least six months.  Councilmembers may be reimbursed from municipal funds for their actual expenses incurred in connection with the affairs of the municipality, if sufficient monies have been appropriated for the purpose.  Reimbursement for expenses shall be allowed in addition to all other compensation to members of the Council, and shall not be deemed to be an increase in salary that is prohibited by this section.
