There must be a leak somewhere for coolant to be depleted. If reserve tank is being depleted, that would mean a leak from radiator cap to cooling system. A pressure test should help you locate the source.
If the reserve tank is not being depleted but is increasing instead, problem would either be a head gasket or radiator cap fault.
